> Key: HBASE-6317
> URL: https://issues.apache.org/jira/browse/HBASE-6317
> Project: HBase
> Issue Type: Bug
> Reporter: ramkrishna.s.vasudevan
> Assignee: rajeshbabu
> Fix For: 0.92.2, 0.96.0, 0.94.1

> Attachments: HBASE-6317_94.patch

> If we have a table in partially enabled state (ENABLING) then on HMaster
> restart we treat it as a clean cluster start up and do a bulk assign.
> Currently in 0.94 bulk assign will not handle ALREADY_OPENED scenarios and it
> leads to region assignment problems. Analysing more on this we found that we
> have better way to handle these scenarios.
> {code}
> if (false == checkIfRegionBelongsToDisabled(regionInfo)
> && false == checkIfRegionsBelongsToEnabling(regionInfo)) {
> synchronized (this.regions) {
> regions.put(regionInfo, regionLocation);
> addToServers(regionLocation, regionInfo);
> }
> {code}
> We dont add to regions map so that enable table handler can handle it. But
> as nothing is added to regions map we think it as a clean cluster start up.
> Will come up with a patch tomorrow.
