Jimmy Xiang commented on HBASE-9204: ------------------------------------ In HBASE-9052, we enhanced AM a little to make split parent not assignable if master is not restarted. I think we can do the same in this case. I can post a patch: put such regions (if any) in split state so that they won't be able to assign from master. > An Offline SplitParent Region can be assigned breaking split references > ----------------------------------------------------------------------- > > Key: HBASE-9204 > URL: https://issues.apache.org/jira/browse/HBASE-9204 > Project: HBase > Issue Type: Bug > Components: Region Assignment > Affects Versions: 0.98.0, 0.95.1, 0.94.10 > Reporter: Matteo Bertozzi > Priority: Blocker > Attachments: HBASE-9294-0.94-v0.patch > > > An offline split parent region can be assigned by using 'assign' from shell. > This may trigger a compaction on the split parent region that should be > offline, breaking the references of the two daughters. > The easy way to test this is: > * disable compactions > * create a table and insert some row > * split > * shutdown the master (otherwise there's a state checked inside the > AssignmentManager) > * start the master > * assign the region marked as OFFLINE => true, SPLIT => true (the compaction > on region startup will probably break the reference of the two daughters) -- This message is automatically generated by JIRA.
