> Replica region needs to check if primary region directory exists at file

> Key: HBASE-24552
> URL: https://issues.apache.org/jira/browse/HBASE-24552
> Project: HBase
> Issue Type: Bug
> Components: read replicas
> Affects Versions: 2.3.0
> Reporter: Huaxiang Sun
> Assignee: Huaxiang Sun
> Priority: Major
>
> In hbase-1, it always runs into the situation that primary region has been
> closed/removed and replica region still stays in master's in-memory db and
> open at one of the region servers. Balancer can move this replica region to a
> new region server. During the region open, replica region does not check if
> primary region has been removed and moves forward. During store open, it will
> recreates primary region directory at hdfs and caused inconsistency.
>
> In hbase-2, things get much better. To prevent the above inconsistency from
> happening, it adds more checks for a replica region, i.e, if primary regions'
> directory exists and there is a .regioninfo under.
