> Issue Type: Bug

>
> 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.
