---------------------------------
Summary: Revisit the executeProcedure method for open/close region
Key: HBASE-21217
URL: https://issues.apache.org/jira/browse/HBASE-21217
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
Fix For: 3.0.0, 2.2.0
Currently we just call openRegion and closeRegion directly, which is a bit
buggy. For example, in order to not fail all the open region requests while
there is only on failure, we will catch the exception and set a flag in the
return value. But for executeProcedures call, the return value will be ignored,
and we expect the openRegion method will always call
reportRegionStateTransition to report the failure but in fact it does not...
And after HBASE-20881, we can confirm that the race could happen, where we send
a close request to a region which is opening(HBASE-21199), and vice visa. So I
think here we need to revisit the implementation of executeProcedures to make
it more stable.
