Duo Zhang commented on HBASE-20700:
-----------------------------------
Yes, the new 'meta' queue will always be served first.
And in RecoverMetaProcedure we will do the log splitting work and assign meta,
so ideally there is no problem if the meta is on a crash RS before. Of course
the logic here is not clear enough I'd say and there maybe races, we can file
new issue to fix it.
And for the new lock, we need to prevent two RMPs run at the same time so I
think we need it...
> Move meta region when server crash can cause the procedure to be stuck
