Compaction/Major compaction operation from shell/API/JMX
--------------------------------------------------------
Key: HBASE-5147
URL: https://issues.apache.org/jira/browse/HBASE-5147
Project: HBase
Issue Type: New Feature
Components: master, regionserver, shell
Affects Versions: 0.90.2, 0.90.1, 0.92.0
Reporter: Mikael Sitruk
Compaction handling is important internal process nevertheless when it occurs
it can have dramatic impact on cluster performance (especially when the cluster
growth uniformly).
Secondly current operations enabled are just to trigger a compaction process
without possibility to know what is its status. Making very unconvenient to
manage compaction manually.
This JIRA suggests to allow management of compaction from different interfaces
- Shell, API, JMX
Following is the list of requested operations
1. getting compaction status - which server/region is under compaction and what
is compacted (currently this info is only via log)
2. % of uncompacted files
3. Possibility to stop major compaction
4. Starting compaction from JMX (other interface already support this)
Note - part of these requirements are also suggested in HBASE-3965
