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

IIRC, 'waitMetaLoaded' will only blocking if the master is fresh started and
region states in the meta table haven't be loaded yet. It will not block SCP
later even if meta region is down.

Yes, I know. Then?

> Project: HBase
> Issue Type: Bug
> Components: proc-v2, Region Assignment
> Reporter: Duo Zhang
> Priority: Blocker
> Fix For: 3.0.0, 2.1.0
>
>
> In HBASE-20700, we make RecoverMetaProcedure use a special lock which is only
> used by RMP to avoid dead lock with MoveRegionProcedure. But we will always
> schedule a RMP when master starting up, so we still need to make sure that
> there is no race between this RMP and other RMPs and SCPs scheduled before
> the master restarts.
