---------------------------------
Summary: Revisit the close region related code at RS side
Key: HBASE-21226
URL: https://issues.apache.org/jira/browse/HBASE-21226
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
We use the closeRegion method to close a region and it will schedule a
CloseRegionHandler(before HBASE-21217). The problem here is that, the
CloseRegionHandler and closeRegion method are mainly designed to be called by
master, but in fact, when shutting down RS, we will also call the closeRegion
method to close all the regions on the RS.
In HBASE-21217, we change to use UnassignRegionHandler to close a region if the
request is from master, so here we need to consider the close region request
when shutting down RS.
