Wellington Chevreuil updated HBASE-22707: ----------------------------------------- Status: Patch Available (was: Open) > [HBCK2] MasterRpcServices assigns method should try to reload regions from > meta if the passed regions isn't found under AssignmentManager > RegionsStateStore > ----------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: HBASE-22707 > URL: https://issues.apache.org/jira/browse/HBASE-22707 > Project: HBase > Issue Type: Task > Components: hbck2, master > Affects Versions: 2.1.5, 2.2.0, 2.3.0 > Reporter: Wellington Chevreuil > Assignee: Wellington Chevreuil > Priority: Major > Fix For: 2.3.0 > > Attachments: HBASE-22707.branch-2.001.patch > > > Although HBCK2 related, this is a master side improvement. On situations > where regions are missing in META, any online fix tool such as the one being > implemented in HBASE-22567 would require a further master restart to get > RegionsStateStore reloaded from META, so that master can be aware of the > newly re-added regions. > After regions are re-added to meta in CLOSED state, it should be possible to > bring those by simply invoking hbck2 _assigns_ command. But before > _MasterRpcServices.assigns_ submits an _Assign_ procedure, it validates first > if the given region is available on _AssignmentManager.RegionsStateStore_. > The current patch reloads meta on _MasterRpcServices.assigns_ if the given > region is not found on the first lookup, then try a new lookup again before > giving-up on region assignment. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
