+# Accumulo Initialization Validation
+
+This document describes the validation mechanisms implemented to ensure Apache Accumulo initializes correctly with Alluxio storage in Kubernetes.
+
+## Overview
+
+The Accumulo Helm chart includes comprehensive validation to ensure:
+
+1. **Alluxio is operational** before Accumulo initialization begins
+2. **Alluxio filesystem is accessible** and writable
+3. **Accumulo instance is properly initialized** in ZooKeeper
+4. **Data directories are created** in Alluxio
+5. **Integration between Accumulo and Alluxio** works correctly
+
+## Prerequisites
+
+The validation mechanisms require:
+
+- **Docker Image**: Accumulo image must include the Alluxio client binaries at `/opt/alluxio/client/bin/alluxio`
+  - The official image includes Alluxio 2.9.4 client, patched for Java 17 compatibility
+  - See [Docker README](../../../docker/README.md) for details on the Alluxio client installation
+  - Note: The Alluxio CLI script is patched during image build to accept Java 17 (required by Accumulo 4.x)
+- **Kubernetes**: Version 1.19+ with proper network connectivity between pods
+- **Helm**: Version 3.2.0+ for deploying the chart
+
+## Validation Layers
+
+### 1. Init Container Validation
+
+The `init-accumulo` container in the manager deployment performs pre-initialization checks:
+
+**Location**: `charts/accumulo/templates/accumulo-manager-deployment.yaml`
+
+**Checks Performed**:
+- ✓ Alluxio Master web UI is accessible (HTTP GET to port 19999)
+- ✓ Alluxio filesystem is accessible (required - fails if not accessible)
+- ✓ Accumulo instance doesn't already exist (idempotent check)
+- ✓ If instance exists: instance_id file must be present in Alluxio (critical check - fails if missing)
+- ✓ Write permissions to Alluxio filesystem
+- ✓ Accumulo initialization completes successfully
+- ✓ instance_id file is created in Alluxio (critical check - fails if missing)
+
+**Example Output (New Installation)**:
+```
+=== Accumulo Initialization Validation ===
+Validating Alluxio connectivity...
+✓ Alluxio master web UI is accessible
+Validating Alluxio filesystem accessibility...
+Alluxio root path: alluxio://accumulo-alluxio-master:19998/accumulo
+✓ Alluxio filesystem is accessible
+Checking if Accumulo instance already exists...
+Initializing new Accumulo instance 'accumulo'...
+Creating Accumulo directory structure in Alluxio...
+Running accumulo init...
+✓ Accumulo initialization completed successfully
+Verifying Accumulo instance_id file in Alluxio...
+✓ Accumulo instance_id file successfully created in Alluxio
+=== Accumulo Initialization Validation Complete ===
+```
+
+**Example Output (Existing Installation)**:
+```
+=== Accumulo Initialization Validation ===
+Validating Alluxio connectivity...
+✓ Alluxio master web UI is accessible
+Validating Alluxio filesystem accessibility...
+Alluxio root path: alluxio://accumulo-alluxio-master:19998/accumulo
+✓ Alluxio filesystem is accessible
+Checking if Accumulo instance already exists...
+✓ Accumulo instance 'accumulo' already exists in ZooKeeper
+Verifying instance_id file exists in Alluxio...
+✓ Accumulo instance_id file found in Alluxio at alluxio://accumulo-alluxio-master:19998/accumulo/instance_id
+```
+
+### 2. Helm Smoke Tests
+
+The Helm smoke test validates the deployed system end-to-end.
+
+**Location**: `charts/accumulo/templates/tests/smoke-test.yaml`
+
+**Tests Performed**:
+- Service availability (ZooKeeper, Alluxio, Accumulo components)
+- Accumulo table operations (create, insert, scan, delete)
+- Alluxio filesystem integration
+- Alluxio cache statistics
+- Monitor web interface accessibility
+
+**Running the Test**:
+```bash
+helm test <release-name>
+kubectl logs <release-name>-smoke-test
+```
+
+### 3. Standalone Validation Script
+
+A comprehensive validation script for manual or automated testing.
+
+**Location**: `scripts/validate-accumulo-init.sh`
+
+**Usage**:
+```bash
+./scripts/validate-accumulo-init.sh <release-name> <namespace> <instance-name>
+
+# Or using Make
+make validate-init RELEASE_NAME=accumulo-dev NAMESPACE=default
+```
+
+**Validation Categories**:
+
+| Category | Checks |
+|----------|--------|
+| **Environment** | kubectl connectivity, Helm release exists |
+| **Pod Status** | All pods running (ZooKeeper, Alluxio, Accumulo) |
+| **Services** | All services have endpoints |
+| **Alluxio** | Master accessible, filesystem responding |
+| **Accumulo Init** | Instance in ZooKeeper, init logs successful |
+| **Integration** | Alluxio client available, data directories exist |
+| **Functionality** | Table operations work |
+
+**Example Output**:
+```

+
+## Troubleshooting
+
+### Init Container Fails
+
+**Check init container logs**:
+```bash
+kubectl logs <manager-pod> -c init-accumulo
+```
+
+**Common issues**:
+- **Alluxio filesystem not accessible**: Initialization will fail immediately. Ensure Alluxio is fully started and accessible.
+- **Instance exists but instance_id file missing**: Critical error indicating corrupted state. See detailed resolution below.
+- **ZooKeeper not accessible**: Check ZooKeeper pod and service
+- **Permissions issues**: Verify service account has proper RBAC permissions
+- **Storage backend not configured**: Check Alluxio mount configuration
+
+#### Critical Error: Instance exists in ZooKeeper but instance_id file not found in Alluxio
+
+This error occurs when Accumulo is registered in ZooKeeper but the critical `instance_id` file is missing from Alluxio:
+
+```bash
+✗ ERROR: Instance exists in ZooKeeper but instance_id file not found in Alluxio
+Expected file: alluxio://accumulo-alluxio-master:19998/accumulo/instance_id
+This indicates a corrupted or incomplete Accumulo installation
+```
+
+**Root Causes**:
+1. Alluxio storage backend was cleared/reset while ZooKeeper data remained
+2. Alluxio mount configuration changed after Accumulo was initialized  
+3. Storage backend credentials or permissions changed
+4. Different storage backend is being used than during initialization
+5. Previous incomplete initialization
+
+**Resolution Steps**:
+
+```bash
+# Step 1: Verify current state
+kubectl exec deployment/accumulo-manager -c manager -- \
+  /opt/accumulo/bin/accumulo org.apache.accumulo.server.util.ListInstances
+
+kubectl exec deployment/accumulo-manager -- \
+  /opt/alluxio/client/bin/alluxio fs ls alluxio://accumulo-alluxio-master:19998/accumulo
+
+# Step 2: Choose resolution approach
+
+# Option A: Clean reinstall (DESTROYS ALL DATA)
+kubectl delete pvc -l app.kubernetes.io/name=zookeeper
+kubectl delete pvc -l app.kubernetes.io/name=minio  # if using MinIO
+helm uninstall accumulo
+helm install accumulo ./charts/accumulo -f values.yaml
+
+# Option B: Fix Alluxio mount (if storage backend exists but mount is wrong)
+# Update values.yaml with correct storage configuration
+helm upgrade accumulo ./charts/accumulo -f corrected-values.yaml
+kubectl delete pod -l app.kubernetes.io/component=alluxio-master
+kubectl delete pod -l app.kubernetes.io/component=manager
+
+# Option C: Restore from backup
+# Restore instance_id and other Accumulo files to Alluxio storage backend
+```
+
+#### Error: Unable to resolve host accumulo-alluxio-worker-XXXXX
+
+This error occurs during Accumulo initialization when trying to write data via Alluxio workers:
+
+```bash
+java.io.IOException: Failed to cache: Unable to resolve host accumulo-alluxio-worker-nbb7g
+```
+
+**Root Cause**: Alluxio workers are advertising individual pod hostnames, but Kubernetes DNS resolution requires fully qualified domain names (FQDNs) for pods behind a headless service.
+
+**Solution**: The chart configures Alluxio workers to use FQDNs in the format:
+```
+<pod-name>.<service-name>.<namespace>.svc.cluster.local
+```
+
+This configuration is already included in the chart. If you encounter this error:
+
+1. **Verify headless service exists**:
+```bash
+kubectl get svc -l app.kubernetes.io/component=alluxio-worker
+# Should show clusterIP: None
+```
+
+2. **Check worker configuration**:
+```bash
+kubectl exec daemonset/accumulo-alluxio-worker -- \
+  cat /opt/alluxio/conf/alluxio-site.properties | grep worker.hostname
+# Should show: alluxio.worker.hostname=<pod>.accumulo-alluxio-worker.<namespace>.svc.cluster.local
+```
+
+3. **Test DNS resolution**:
+```bash
+kubectl run test --rm -it --image=busybox --restart=Never -- \
+  nslookup <pod-name>.accumulo-alluxio-worker.<namespace>.svc.cluster.local
+```
+
+4. **If DNS fails**, ensure:
+   - CoreDNS or kube-dns is running properly
+   - Network policies allow DNS queries
+   - Pod's `/etc/resolv.conf` has correct search domains
+
+5. **Restart workers if needed**:
+```bash
+kubectl rollout restart daemonset accumulo-alluxio-worker
+```
+```
+
+### Smoke Test Fails
+
+**Check test logs**:
+```bash
+kubectl logs <release-name>-smoke-test
+```
+
+**Common issues**:
+- Services not ready: Wait longer for all pods to be Running
+- Authentication failures: Verify instance secret is correct
+- Alluxio mount failures: Check storage backend configuration
+- Network policies: Ensure pods can communicate
+
+### Validation Script Warnings
+
+**Review specific warnings**:
+- Warnings typically indicate non-critical issues
+- Check if reduced functionality is acceptable
+- Some checks may fail in restricted environments
+
+## Best Practices
+
+1. **Always run validation** after deployment:
+   ```bash
+   make validate-init RELEASE_NAME=<release>
+   ```
+
+2. **Check init logs** if there are issues:
+   ```bash
+   kubectl logs <manager-pod> -c init-accumulo
+   ```
+
+3. **Run smoke tests** to verify functionality:
+   ```bash
+   helm test <release-name>
+   ```
+
+4. **Monitor Alluxio** cache hit rates:
+   ```bash
+   kubectl port-forward svc/<release>-alluxio-master 19999:19999
+   curl http://localhost:19999/metrics
+   ```
+
+5. **Validate before upgrades**:
+   - Run validation script before upgrading
+   - Back up ZooKeeper data
+   - Verify Alluxio storage is accessible
+

+# Accumulo Helm Chart Tests
+
+This directory contains documentation for Helm test manifests for validating the Accumulo deployment with Alluxio integration.
+
+The actual test manifests are located in `templates/tests/` directory.
+
+## Available Tests
+
+### Smoke Test (`templates/tests/smoke-test.yaml`)
+
+The smoke test performs comprehensive validation of the Accumulo cluster with Alluxio storage.
+
+**Test Scope**:
+- Service connectivity and availability
+- Accumulo table operations (CRUD)
+- Alluxio filesystem integration
+- Data persistence through Alluxio
+- Monitor web interface
+
+**Running the Test**:
+```bash
+# Run all tests
+helm test <release-name>
+
+# Run tests with timeout
+helm test <release-name> --timeout 10m
+
+# View test logs
+kubectl logs <release-name>-smoke-test
+
+# Clean up test pods
+kubectl delete pod <release-name>-smoke-test
+```
+
+## Test Execution Flow
+
+```
+1. Wait for Services (init container)
+   ├─ ZooKeeper ready (port 2181)
+   ├─ Alluxio master ready (port 19998)
+   ├─ Accumulo manager ready (port 9999)
+   └─ TabletServer ready (port 9997)
+
+2. Test Accumulo Operations (main container)
+   ├─ Create test table
+   ├─ Insert test data (3 rows)
+   ├─ Scan and verify data
+   ├─ Flush table
+   └─ Compact table
+
+3. Test Alluxio Integration
+   ├─ Check Alluxio master web UI
+   ├─ Verify data directories in Alluxio
+   ├─ List Accumulo directories
+   └─ Check Alluxio cache metrics
+
+4. Test Monitor Interface
+   └─ Access Monitor web UI (port 9995)
+
+5. Cleanup
+   └─ Delete test table
+```
+
+## Test Configuration
+
+Tests are configured through Helm values:
+
+```yaml
+dev:
+  smokeTest:
+    enabled: true
+    image:
+      registry: docker.io
+      repository: accumulo/accumulo
+      tag: "4.0.0-SNAPSHOT"
+```
+
+To disable tests:
+```yaml
+dev:
+  smokeTest:
+    enabled: false
+```
+
+## Test Results
+
+### Success Criteria
+
+All of the following must pass:
+- ✓ All services are accessible
+- ✓ Test table created successfully
+- ✓ 3 test rows inserted and verified
+- ✓ Table operations (flush, compact) complete
+- ✓ Alluxio master responds to HTTP requests
+- ✓ Accumulo directories exist in Alluxio
+- ✓ Monitor web interface is accessible
+- ✓ Test table deleted successfully
+
+### Common Test Failures
+
+#### 1. Service Timeout
+```
+Waiting for <service>...
+Error: timed out waiting for the condition
+```
+
+**Resolution**:
+- Increase test timeout: `helm test --timeout 15m`
+- Check pod status: `kubectl get pods`
+- Verify services: `kubectl get endpoints`
+
+#### 2. Table Creation Fails
+```
+FAILED: Could not create table
+```
+
+**Resolution**:
+- Check manager logs: `kubectl logs deployment/<release>-manager`
+- Verify ZooKeeper connectivity
+- Check Alluxio mount status
+
+#### 3. Alluxio Integration Fails
+```
+WARNING: Could not verify Accumulo data in Alluxio
+```
+
+**Resolution**:
+- Check Alluxio master logs: `kubectl logs deployment/<release>-alluxio-master`
+- Verify storage backend configuration
+- Check Alluxio mount: `kubectl exec <manager-pod> -- /opt/alluxio/client/bin/alluxio fs ls /`
+
+#### 4. Data Verification Fails
+```
+FAILED: Expected 3 rows, found <n>
+```
+
+**Resolution**:
+- Check TabletServer logs: `kubectl logs deployment/<release>-tserver`
+- Verify write operations completed
+- Check for compaction issues
+
+## Manual Testing
+
+For manual testing outside of Helm tests:
+
+```bash
+# Access Accumulo shell
+kubectl exec -it deployment/<release>-manager -- \
+  /opt/accumulo/bin/accumulo shell -u root -p <password>
+
+# Run Accumulo commands
+createtable testtable
+insert row1 cf1 cq1 value1
+scan
+deletetable -f testtable
+quit
+
+# Check Alluxio filesystem
+kubectl exec deployment/<release>-manager -- \
+  /opt/alluxio/client/bin/alluxio fs ls /accumulo
+
+# Test Alluxio master
+kubectl port-forward svc/<release>-alluxio-master 19999:19999
+curl http://localhost:19999/
+
+# Test Monitor
+kubectl port-forward svc/<release>-monitor 9995:9995
+curl http://localhost:9995/
+```

+# Accumulo Docker Image
+
+This directory contains the Dockerfile and scripts for building Apache Accumulo container images with Alluxio integration.
+
+## Features
+
+The Docker image includes:
+- Apache Accumulo 4.0.0-SNAPSHOT
+- Hadoop 3.3.6 client libraries
+- ZooKeeper 3.8.4 client libraries
+- **Alluxio 2.9.4 client (binaries + JARs)** for filesystem integration, patched for Java 17 compatibility
+- Java 17 (Eclipse Temurin)
+
+**Note**: Alluxio 2.9.4 is patched to accept Java 17. The original version only officially supports Java 8 or 11, but the client JARs work correctly with Java 17 for basic filesystem operations. The alluxio CLI script is patched during image build to accept Java 17.
+
+### Alluxio Client Integration
+
+The image includes the full Alluxio client installation at `/opt/alluxio/client`:
+- **CLI Tool**: `/opt/alluxio/client/bin/alluxio` - Command-line interface for Alluxio filesystem operations
+- **Client JARs**: `/opt/alluxio/client/*.jar` - Alluxio client libraries copied to Accumulo's classpath
+- **Libraries**: `/opt/alluxio/client/lib/` - Required dependencies for the CLI tool
+- **Configuration**: `/opt/alluxio/client/conf/` - Alluxio configuration files
+- **Scripts**: `/opt/alluxio/client/libexec/` - Helper scripts required by the CLI (alluxio-config.sh, etc.)
+
+This enables:
+1. Accumulo to read/write data to Alluxio filesystem via the client JARs
+2. Init containers to validate Alluxio connectivity using the `alluxio fs` CLI commands
+3. Troubleshooting and debugging with direct Alluxio filesystem access
+
+## Building the Image
+
+```bash
+# Build from the repository root
+cd /path/to/veculo
+./scripts/build-docker.sh -r accumulo -t 4.0.0-SNAPSHOT
+
+# Or build manually
+cd docker/accumulo
+docker build -t accumulo/accumulo:4.0.0-SNAPSHOT .
+```
+
+## Loading into Minikube
+
+```bash
 minikube image load accumulo/accumulo:4.0.0-SNAPSHOT
+```
+
+## Environment Variables
+
+- `ACCUMULO_HOME=/opt/accumulo`
+- `HADOOP_HOME=/opt/hadoop/hadoop-3.3.6`
+- `ZOOKEEPER_HOME=/opt/zookeeper`
+- `ALLUXIO_HOME=/opt/alluxio/client`
+- `ALLUXIO_CLIENT_HOME=/opt/alluxio/client`
+- `JAVA_HOME=/opt/java/openjdk`
+
+## Using the Alluxio Client
+
+Inside the container:
+
+```bash
+# List Alluxio filesystem
+/opt/alluxio/client/bin/alluxio fs ls /
+
+# Check if a file exists
+/opt/alluxio/client/bin/alluxio fs test -e /path/to/file
+
+# Create directory
+/opt/alluxio/client/bin/alluxio fs mkdir /path/to/dir
+```

+### `validate-accumulo-init.sh`
+Validates that Accumulo has been properly initialized with Alluxio storage.
+
+**Usage:**
+```bash
+# Validate with default parameters
+./scripts/validate-accumulo-init.sh
+
+# Validate specific release
+./scripts/validate-accumulo-init.sh accumulo-prod production accumulo-instance
+
+# Use with Make
+make validate-init RELEASE_NAME=accumulo-dev NAMESPACE=default
+```
+
+**Validates:**
+- Kubernetes cluster connectivity
+- Helm release exists
+- All required pods are running (ZooKeeper, Alluxio, Accumulo components)
+- Services have proper endpoints
+- Alluxio Master is accessible
+- Accumulo instance is initialized in ZooKeeper
+- Alluxio filesystem integration is working
+- Accumulo data directories exist in Alluxio
+- Alluxio client libraries are available
+
+**Exit Codes:**
+- `0`: All critical validations passed
+- `1`: One or more critical validations failed
+
