Duo Zhang commented on HBASE-20881: ----------------------------------- Another problem is SplitTableRegionProcedure and MergeTableRegionProcedure, as they will also hold the exclusive lock for the regions, but can not be interrupted by SCP. > Introduce a region transition procedure to handle all the state transition > for a region > --------------------------------------------------------------------------------------- > > Key: HBASE-20881 > URL: https://issues.apache.org/jira/browse/HBASE-20881 > Project: HBase > Issue Type: Sub-task > Reporter: Duo Zhang > Priority: Major > > Now have an AssignProcedure, an UnssignProcedure, and also a > MoveRegionProcedure which schedules an AssignProcedure and an > UnssignProcedure to move a region. This makes the logic a bit complicated, as > MRP is not a RIT, so when SCP can not interrupt it directly... -- This message was sent by Atlassian JIRA (v7.6.3#76005)
