> In DummyStoreOperator the row is cached to fix HIVE-5973. The row is copyed and stored
in the writable format, but the object inspector is initialized to default. So when join operator
is fetching the data from dummy store operator, its getting the OI is Long and the row as
LongWritable. This is causing the class cast exception.
