    Description

      Hive doesn't have integration with Hadoop's OutputCommitter, it uses a NullOutputCommitter and uses its own commit logic spread across FileSinkOperator, MoveTask, and Hive.

      The Hadoop community is building an OutputCommitter that integrates with S3Guard and does a safe, coordinate commit of data on S3 inside individual tasks (HADOOP-13786). If Hive can integrate with this new OutputCommitter there would be a lot of benefits to Hive-on-S3:

      • Data is only written once; directly committing data at a task level means no renames are necessary
      • The commit is done safely, in a coordinated manner; duplicate tasks (from task retries or speculative execution) should not step on each other
