Description

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
