Matteo Bertozzi commented on HBASE-9207: ---------------------------------------- +1, v3 looks good to me, doing some testing I ended up with the client stuck waiting for the offline region to be available HBASE-9233. so an older client talking to a newer server with this patch may end up waiting until the timeout. but that is only in the case of meta recovery, and in my opinion is better waiting a bit longer instead of assigning a parent region and break the daughter' references. > An Offline SplitParent Region can be assigned breaking split references > ----------------------------------------------------------------------- > > Key: HBASE-9207 > URL: https://issues.apache.org/jira/browse/HBASE-9207 > Project: HBase > Issue Type: Bug > Components: Region Assignment > Affects Versions: 0.98.0, 0.95.1, 0.94.10 > Reporter: Matteo Bertozzi > Assignee: Jimmy Xiang > Fix For: 0.94.12 > > Attachments: 0.94-9204.patch, 0.94-9204_v2.patch, 0.94-9207_v3.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.
