Subject [jira] [Created] (HBASE-12446) [list | abort] Compactions
Date Fri, 07 Nov 2014 22:42:35 GMT
Manukranth Kolloju created HBASE-12446:
------------------------------------------

             Summary: [list | abort] Compactions
                 Key: HBASE-12446
                 URL: https://issues.apache.org/jira/browse/HBASE-12446
             Project: HBase
          Issue Type: New Feature
    Affects Versions: 1.0.0
            Reporter: Manukranth Kolloju
             Fix For: 1.0.0


In some cases, we would need to quickly reduce load on a server without killing it. Compactions
is one of the critical processes which takes up a lot of CPU and disk IOPS. We should have
a way to list compactions given the regionserver and abort compactions given regionserver
and compaction id. And additionally abort all compactions. 

Pardon me if there was already a similar Jira, I'd be happy to merge this there.

The current code handles interrupts. We should be able to interrupt the thread that is performing
the compaction and abort it from either the UI or from the command line. This Jira is targeted
to expose an admin function to perform such a task.
