Hari Sekhon commented on HBASE-6028:
------------------------------------

I'm on site with a client that also wants this ability to cancel compactions, 
any chance this will get resolved soon?

If there is something in the API (and preferably also exposed in the HBase 
Shell) to allow it a 'cancel_compaction' command then that would be really, 
really useful.

> 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
