HDP 2.0 and Cassandra

  • #43891


    I am newbie to Cassandra and HDP 2.0.

    I have installed a single node Cassandra 2.0.2 (Datastax Community Edition) in one of the data nodes of my 3 node HDP 2.0 cluster.

    I am unable to use hive to access Cassandra using ‘org.apache.hadoop.hive.cassandra.cql3.CqlStorageHandler’. I am getting the error ‘ return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.ql.metadata.HiveException: Error in loading storage handler.org.apache.hadoop.hive.cassandra.cql3.CqlStorageHandler’

    I have copied all the jars in /$cassandra_home/lib/* to /$hive-home/lib and also included the /cassandra_home/lib/* in the $HADOOP_CLASSPATH.

    Is there any other configuration changes that I have to make to integrate Cassandra with Hadoop?

    Please let me know. Thanks for the help!
