Ted Yu commented on HBASE-9485:
-------------------------------
Patch v2 adds recovery related methods to TableOutputCommitter.
For HBase, there is no intermediate table - we write to the target table
directly.
> TableOutputCommitter should implement recovery if we don't want jobs to start
> from 0 on RM restart

> HBase extends OutputCommitter which turns recovery off. Meaning all completed
> maps are lost on RM restart and job starts from scratch. FileOutputCommitter
> implements recovery so we should look at that to see what is potentially
> needed for recovery.
