> HBCK incorrectly reports inconsistencies for recently split regions following
> a master failover
> -----------------------------------------------------------------------------------------------
>
> Key: HBASE-26383
> URL: https://issues.apache.org/jira/browse/HBASE-26383
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 2.4.3
> Reporter: Benoit Sigoure
> Assignee: Andrew Kyle Purtell
> Priority: Critical
> Fix For: 2.5.0, 3.0.0-alpha-2, 2.4.8
>
>
> When a region P splits into A and B, following a master failover the newly
> active master reports that P is in an inconsistent state. This seems to be a
> regression introduced in HBASE-25847 (cc [[email protected]]) which
> changed {{regionInfo.isParentSplit()}} to {{regionState.isSplit()}}. The
> region state after restart is CLOSED (rather than SPLIT), so both region
> state and region info should be checked, presumably with
> {{regionState.isSplit() || regionInfo.isSplit()}}. This situation resolves
> itself on its own when a major compaction occurs and P is GCed, but having
> the master incorrectly report inconsistencies is pretty bad. We had a pretty
> big outage due to a series of operator errors as our SRE team was trying to
> fix this inconsistency that, in fact, didn't even exist.
> Thanks to Stack for helping look over this issue and Vlad Hanciuta for root
> causing the bug.
