> 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
> Components: amv2, proc-v2
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Critical
> Fix For: 3.0.0, 2.2.0

> Attachments: HBASE-21217-v1.patch, HBASE-21217-v2.patch,
> HBASE-21217.patch

> 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 one 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.
