Huaxiang Sun updated HBASE-24552: --------------------------------- Summary: Replica region needs to check if primary region exists in hdfs in TransitRegionStateProcedure (was: Replica region needs to dcheck if primary region exists in hdfs in TransitRegionStateProcedure ) > Replica region needs to check if primary region exists in hdfs in > TransitRegionStateProcedure > ---------------------------------------------------------------------------------------------- > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
