Jingcheng Du updated HBASE-11861:
---------------------------------
Attachment: HBASE-11861-V3.diff
Update the patch according the comments in RB. Thanks.
Two improvements still need to be done.
1. Add thread pool to the compactor to merging the small files in different
partition in parallel.
2. Need more unit tests.
> Native MOB Compaction mechanisms.

> Currently, the first cut of mob will have external processes to age off old
> mob data (the ttl cleaner), and to compact away deleted or over written data
> (the sweep tool).
> From an operational point of view, having two external tools, especially one
> that relies on MapReduce is undesirable. In this issue we'll tackle
> integrating these into hbase without requiring external processes.
