Description

Reproduction:

1. Create a table with region replication, and ensure that the primary region and replica region are on the same RS (eg: the HBase cluster has only one RS)
create 't01', 'info', {REGION_REPLICATION => 2}

2. The first region does not split when storefile size exceed  flushsize * 2, because that we get 2 regions about this table on this RS (1 primary region and 1 replica region)

 

I think we should ignore the replica reggion when getting the count of regions on this same regionserver.

Is my idea correct? maybe can discuss it .
