ramkrishna.s.vasudevan updated HBASE-5927: ------------------------------------------ Summary: SSH and DisableTableHandler happening together does not clear the znode of the region and RIT map. (was: AM#unassign should handle local exceptions after calling sendRegionClose) > SSH and DisableTableHandler happening together does not clear the znode of > the region and RIT map. > -------------------------------------------------------------------------------------------------- > > Key: HBASE-5927 > URL: https://issues.apache.org/jira/browse/HBASE-5927 > Project: HBase > Issue Type: Bug > Components: master > Affects Versions: 0.92.1, 0.96.0, 0.94.1 > Reporter: Jieshan Bean > Assignee: Jieshan Bean > Fix For: 0.92.2, 0.96.0, 0.94.1 > > Attachments: TestCaseForReProduce.txt > > > A possible exception: If the related regionserver was just killed(But HMaster > has not perceived that), then we will get a local exception "Connection reset > by peer". If this region belongs to a disabling table. what will happen? > ServerShutdownHandler will remove this region from AM#regions. So this region > is still existing in RIT. TimeoutMonitor will take care of it after it got > timeout. Then invoke unassign again. Since this region has been removed from > AM#regions, it will return directly due to the below code: > {code} > synchronized (this.regions) { > // Check if this region is currently assigned > if (!regions.containsKey(region)) { > LOG.debug("Attempted to unassign region " + > region.getRegionNameAsString() + " but it is not " + > "currently assigned anywhere"); > return; > } > } > {code} > Then it leads to an end-less loop. -- This message is automatically generated by JIRA.
