> I found this problem when I write ut for HBASE-20569. Now the master
> finishActiveMasterInitialization introduce a new
> RecoverMetaProcedure(HBASE-18261) and it has a sub procedure AssignProcedure.
> AssignProcedure will skip assign a region when regions state is OPEN and
> server is online. But for the new regiog state node is created with state
> OFFLINE. So it will assign the meta to a new RS. And kill the old RS when old
> RS report to master. This will make the master initialization cost a long
> time. I will attatch a ut to show this. FYI [~stack]
