Umesh Agashe commented on HBASE-6028:
-------------------------------------

2 of the rubocop messages are about 'Line too long'. Rest of the ruby code has 
100 chars wide lines, rubocop expects 80. These messages can be ignored. Unit 
test failure 'TestSyncReplicationStandbyKillMaster' doesn't seem to be related 
to the changes. Retrying the build.

> Implement a cancel for in-progress compactions

> 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
