> 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
