Nick Dimiduk commented on HBASE-9485:
-------------------------------------
This patch sets explicitly that recovery is not supported. How do you intend to
add support for recovery without a global ordering of records to write and a
status tracking successful puts?
Nit: please include the @Override annotations on the methods.
> 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.
