[jira] [Created] (HIVE-19946) VectorizedRowBatchCtx.recordIdColumnVector cannot be shared between different JVMs

Teddy Choi created HIVE-19946:
---------------------------------

             Summary: VectorizedRowBatchCtx.recordIdColumnVector cannot be shared between different JVMs
                 Key: HIVE-19946
                 URL: https://issues.apache.org/jira/browse/HIVE-19946
             Project: Hive
          Issue Type: Bug
            Reporter: Teddy Choi
            Assignee: Teddy Choi


VectorizedRowBatchCtx.recordIdColumnVector was used temporarily to pass record id column, which is virtual, between a reducer and a mapper. However, when the reducer and the mapper are not in a same JVM, it makes incorrect results.
