[jira] [Commented] (HBASE-23079) RegionRemoteProcedureBase should
override setTimeoutFailure
[ https://issues.apache.org/jira/browse/HBASE-23079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16940590#comment-16940590 ]
Xiaolin Ha commented on HBASE-23079:
------------------------------------
Got it. So it's because the ORP be marked as WAITING_TIMEOUT and enters the rollback logic.
Thanks.

> Key: HBASE-23079
> URL: https://issues.apache.org/jira/browse/HBASE-23079
> Project: HBase
> Issue Type: Bug
> Components: amv2
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Blocker
> Fix For: 3.0.0, 2.3.0, 2.2.2
>
>
> In our test environment, we found that, when OpenRegionProcedure failed by timeout, though it doesn't support rollback, ProcedureExcutor will delete the OPR node in the store in its own rollback steps and make the RIT stay there looping rollback exception. ServerCrashProcedure will detect this RIT but cannot deal with it, because no node in the store and it will encounters NPE, as a result, SCP aborts.
