 # Use Apache Spark to read and write Apache HBase data
 
-Apache HBase is typically queried either with its low-level API (scans, gets, and puts) or with a SQL syntax using Apache Phoenix. Apache also provides the Apache Spark HBase Connector, which is a convenient and performant alternative to query and modify data stored by HBase.

 ## Prerequisites
 
 * Two separate HDInsight clusters deployed in the same [virtual network](./hdinsight-plan-virtual-network-deployment.md). One HBase, and one Spark with at least Spark 2.1 (HDInsight 3.6) installed. For more information, see [Create Linux-based clusters in HDInsight using the Azure portal](hdinsight-hadoop-create-linux-clusters-portal.md).
 
-* An SSH client. For more information, see [Connect to HDInsight (Apache Hadoop) using SSH](hdinsight-hadoop-linux-use-ssh-unix.md).
-
-* The [URI scheme](hdinsight-hadoop-linux-information.md#URI-and-scheme) for your clusters primary storage. This scheme would be wasb:// for Azure Blob Storage, abfs:// for Azure Data Lake Storage Gen2 or adl:// for Azure Data Lake Storage Gen1. If secure transfer is enabled for Blob Storage, the URI would be `wasbs://`.  See also, [secure transfer](../storage/common/storage-require-secure-transfer.md).

      b. Identify the rowkey as `key`, and map the column names used in Spark to the column family, column name, and column type as used in HBase.
