Summary: CompactSplit attempts to split non-default regions (was:
CompactSplit should not attempt to split non-default regions)

> Project: HBase
> Issue Type: Bug
>Reporter: Charles Connell
>Assignee: Charles Connell
>Priority: Minor
>
> I discovered a problem while running a large cluster with region replicas
> enabled. From time to time, WAL flushes trigger splits, and when the region
> being split is a secondary replica, this split causes problems. The
> {{SplitTableRegionProcedure}} does not permit splitting secondary replicas.
> The RegionServer will send a {{ReportRegionStateTransitionRequest}} to the
> HMaster, which will send back an error response, logging as it does so:

> As a result, the RegionServer will retry the
> {{ReportRegionStateTransitionRequest}} infinitely. The RegionServer is doing
> this in a thread pool task that nothing is waiting on, so it's not really
> bothered by this. In a large cluster, the HMaster request handling threads
> its the logging system will eventually become saturated by the volume of
> these requests coming from many RegionServers.
