stack commented on HBASE-6028:
------------------------------
IIRC, there already is a cancel facility that is used on region close; if an
ongoing compaction, its interrupted. If such is the case, this issue would
hopefully just be about exposing this functionality in hbase admin (Sorry D,
should have remembered today that we do this).
> Implement a cancel for in-progress compactions

> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Reporter: Derek Wollenstein
> Priority: Minor
> Labels: compaction, operations, regionserver
>
> Depending on current server load, it can be extremely expensive to run
> periodic minor / major compactions. It would be helpful to have a feature
> where a user could use the shell or a client tool to explicitly cancel an
> in-progress compactions. This would allow a system to recover when too many
> regions became eligible for compactions at once
