Subject [jira] [Created] (HBASE-5147) Compaction/Major compaction operation from shell/API/JMX
Date Sun, 08 Jan 2012 22:02:39 GMT
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
