stack commented on HBASE-19976:
-------------------------------
No, I'm wrong, RecoverMetaProcedure implements TableProcedureInterface. Do you
have thread dump of all stuck Procedures waiting on Master [~Apache9] ? Can I
break up this step so RecoverMetaProcedure has a chance to run?
> Dead lock if the worker threads in procedure executor are exhausted

> See the comments in HBASE-19554. If all the worker threads are stuck in
