---------------------------------

             Summary: [WAL] RegionGroupingStrategy loses its function after 
split
                 Key: HBASE-22774
                 URL: https://issues.apache.org/jira/browse/HBASE-22774
             Project: HBase
          Issue Type: Bug
            Reporter: Reid Chan
            Assignee: Reid Chan


Having {{hbase.wal.provider}} set {{multiwal}}, it works fine on regionserver 
restart, at the beginning.

But when region split happened, those daughter regions would inherit her 
parent's WAL, which violates the setting. For example, when 
{{hbase.wal.regiongrouping.strategy}} set {{identity}}, each daughter regions 
should create its own WAL instead of inheriting.
