cassandra - FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask -

I'm using datastax 4.5 and I have enabled hasoop and spark on a node. Now when I execute the quiz in the hive shell, I get an error

Failure: Execution error, return code from org.apache.hadoop.hive.ql.exec.DDLTask 1. Java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

Please tell me what I am.

thanks
