[HBASE-6028] Implement a cancel for in-progress compactions

• Type: Bug
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Fix Version/s: 3.0.0-alpha-1, 2.2.0
• Component/s: regionserver
• Labels: beginner pull-request-available

Release Note

Added a new command to the shell to switch on/off compactions called "compaction_switch". Disabling compactions will interrupt any currently ongoing compactions. This setting will be lost on restart of the server. Added the configuration hbase.regionserver.compaction.enabled so user can enable/disable compactions via hbase-site.xml.

Description

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
