Duo Zhang commented on HBASE-20700:
-----------------------------------
OK seems letting meta online first can make life much easier...
So I think we could do the following:
1. Introduce a new type of queue in MasterProcedureScheduler called meta, only
RecoverMetaProcedure can be put into this queue.
2. Introduce a new type of lock for RMP, do not use table lock any more so that
RMP will not be blocked by MRP.
3. MasterProcedureScheduler will be started with a flag which only enable
polling procedures out from meta queue, and after the meta region is online, we
disable the flag and then everything back to normal.
> Move meta region when server crash can cause the procedure to be stuck
