Description
After HBASE-20708, we changed the way we init after master starts. It will only check WAL dirs and compare to Zookeeper RS nodes to decide which server need to expire. For servers which's dir is ending with 'SPLITTING', we assure that there will be a SCP for it.
But, if the server with the meta region crashed before master restarts, and if all the procedure wals are lost (due to bug, or deleted manually, whatever), the new restarted master will be stuck when initing. Since no one will bring meta region online.
Although it is an anomaly case, but I think no matter what happens, we need to online meta region. Otherwise, we are sitting ducks, noting can be done.
