---------------------------------

             Summary: Writable object inspector should use Writable classes from Hadoop for
get
                 Key: HIVE-9314
                 URL: https://issues.apache.org/jira/browse/HIVE-9314
             Project: Hive
          Issue Type: Improvement
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang
            Priority: Minor


In WritableByteObjectInspector, we cast objects to org.apache.hadoop.hive.serde2.io.ByteWritable
 to get the value. We should use the hadoop one since org.apache.hadoop.hive.serde2.io.ByteWritable
extends the hadoop one.

If customer OI uses the hadoop writable, in some queries, they could get class cast exception.
