> 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.
