Using Spark Hive Warehouse and HBase Connector Client .jar files with Livy

This section describes how to use Spark Hive Warehouse Connector (HWC) and HBase-Spark connector client .jar files with Livy. These steps are required to ensure token acquisition and avoid authentication errors.

Use the following steps to use Spark HWC and HBase-Spark client .jar files with Livy:

  1. Copy the applicable HWC or HBase-Spark .jar files to the Livy server node and add these folders to the livy.file.local-dir-whitelist property in the livy.conf file.
  2. Add the required Hive and HBase configurations in the Spark client configuration folder:
    • Hive:

      For Spark 2 — /etc/spark/conf/hive-site.xml

      For Spark 3 — /etc/spark3/conf/hive-site.xml

    • HBase:

      For Spark 2 — /etc/spark/conf/hbase-site.xml

      For Spark 3 — /etc/spark3/conf/hbase-site.xml

    Or add the required configurations using the conf field in the session creation request. This is equivalent to using "--conf" in spark-submit.
  3. Reference these local .jar files in the session creation request using the file:/// URI format.

HWC Example

  1. In Cloudera Manager, go to Clusters > Livy.
  2. Click the Configuration tab and search for the "Livy Server Advanced Configuration Snippet (Safety Valve) for livy-conf/livy.conf" property.
  3. Add the /opt/cloudera/parcels/CDH-<version>/jars folder to the livy.file.local-dir-whitelist property in the livy.conf file.

  4. Save the changes and restart the Livy service.
  5. Log in to the Zeppelin Server Web UI and restart the Livy interpreter.
  6. When running the Zeppelin Livy interpreter, reference the HWC .jar file as shown below.
    • For Spark 2:
      livy.spark.jars file:///opt/cloudera/parcels/CDH-<version>/jars/hive-warehouse-connector-assembly-<version>.jar
    • For Spark 3:
      livy.spark.jars file:///opt/cloudera/parcels/CDH-<version>/jars/hive-warehouse-connector-spark3-assembly-<version>.jar

HBase-Spark Connector Example

  1. When running the Zeppelin Livy interpreter, reference the following HBase .jar files as shown below. Note that some of these .jar files have 644/root permissions, and therefore may throw an exception. If this happens, you may need to change the permissions of the applicable .jar files on the Livy node.
    livy.spark.jars file:///opt/cloudera/parcels/CDH-<version>/jars/hbase-spark3-
