Thanks all for reviewing. > The checkOnlineRegionsReport can accidentally complete a TRSP > ------------------------------------------------------------- > > Key: HBASE-21463 > URL: https://issues.apache.org/jira/browse/HBASE-21463 > Project: HBase > Issue Type: Sub-task > Components: amv2 > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Critical > Fix For: 3.0.0, 2.2.0 > > Attachments: HBASE-21463-UT.patch, HBASE-21463-v1.patch, > HBASE-21463-v2.patch, HBASE-21463.patch > > > On our testing cluster, we observe a race condition: > 1. A regionServerReport request is built > 2. A TRSP is scheduled to reopen the region > 3. The region is closed at RS side > 4. The OpenRegionProcedure is created > 5. The regionServerReport generated at step 1 is executed, and we find that > the region is opened on the RS, so we update the region state to OPEN. > 6. The OpenRegionProcedure notices that the region has already been in the > OPEN state so gives up and finishes. > 7. The TRSP finishes. > 8. The region is recorded as OPEN on the RS but actually not, and can not > recover unless we use HBCK2. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
