[jira] [Updated] (HBASE-22061) SplitTableRegionProcedure should hold the lock of its daughter regions

     [ https://issues.apache.org/jira/browse/HBASE-22061?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jingyun Tian updated HBASE-22061:
---------------------------------
    Description: 
Currently SplitTableRegionProcedure only hold the region of parent region. But during processing of this procedure, after the daughter regions are updated to meta, other procedures can grab the lock of them, which is the situation we don't want to see.
 So I think SplitTableRegionProcedure should hold the lock of parent region and its daughter regions like MergeTableRegionsProcedure holding the lock of merged region.
