PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🧪 No relevant tests

🔒 No security concerns identified

✅ No TODO sections

🔀 No multiple PR themes

⚡ Recommended focus areas for review Same Bug URL All four muted tests (testHighCPUInEnforcedMode, testHighCPUInMonitorMode, testHighMemoryInEnforcedMode, testHighMemoryInMonitorMode) point to the same bug URL (issue #17154). Based on the PR description, the failures appear to have different characteristics (CPU vs Memory, Enforced vs Monitor mode). It should be verified that a single issue truly covers all four test failures, or if separate tracking issues are needed. @AwaitsFix(bugUrl = "https://github.com/opensearch-project/OpenSearch/issues/17154") public void testHighCPUInEnforcedMode() throws InterruptedException { Settings request = Settings.builder().put(WorkloadManagementSettings.WLM_MODE_SETTING.getKey(), ENABLED).build(); assertAcked(client().admin().cluster().prepareUpdateSettings().setPersistentSettings(request).get()); WorkloadGroup workloadGroup = new WorkloadGroup( "name", new MutableWorkloadGroupFragment( MutableWorkloadGroupFragment.ResiliencyMode.ENFORCED, Map.of(ResourceType.CPU, 0.01, ResourceType.MEMORY, 0.01) ) ); updateWorkloadGroupInClusterState(PUT, workloadGroup); Exception caughtException = executeWorkloadGroupTask(CPU, workloadGroup.get_id()); assertNotNull("SearchTask should have been cancelled with TaskCancelledException", caughtException); MatcherAssert.assertThat(caughtException, instanceOf(TaskCancelledException.class)); updateWorkloadGroupInClusterState(DELETE, workloadGroup); } @AwaitsFix(bugUrl = "https://github.com/opensearch-project/OpenSearch/issues/17154") public void testHighCPUInMonitorMode() throws InterruptedException { WorkloadGroup workloadGroup = new WorkloadGroup( "name", new MutableWorkloadGroupFragment( MutableWorkloadGroupFragment.ResiliencyMode.ENFORCED, Map.of(ResourceType.CPU, 0.01, ResourceType.MEMORY, 0.01) ) ); updateWorkloadGroupInClusterState(PUT, workloadGroup); Exception caughtException = executeWorkloadGroupTask(CPU, workloadGroup.get_id()); assertNull(caughtException); updateWorkloadGroupInClusterState(DELETE, workloadGroup); } @AwaitsFix(bugUrl = "https://github.com/opensearch-project/OpenSearch/issues/17154") public void testHighMemoryInEnforcedMode() throws InterruptedException { Settings request = Settings.builder().put(WorkloadManagementSettings.WLM_MODE_SETTING.getKey(), ENABLED).build(); assertAcked(client().admin().cluster().prepareUpdateSettings().setPersistentSettings(request).get()); WorkloadGroup workloadGroup = new WorkloadGroup( "name", new MutableWorkloadGroupFragment(MutableWorkloadGroupFragment.ResiliencyMode.ENFORCED, Map.of(ResourceType.MEMORY, 0.01)) ); updateWorkloadGroupInClusterState(PUT, workloadGroup); Exception caughtException = executeWorkloadGroupTask(MEMORY, workloadGroup.get_id()); assertNotNull("SearchTask should have been cancelled with TaskCancelledException", caughtException); MatcherAssert.assertThat(caughtException, instanceOf(TaskCancelledException.class)); updateWorkloadGroupInClusterState(DELETE, workloadGroup); } @AwaitsFix(bugUrl = "https://github.com/opensearch-project/OpenSearch/issues/17154")
