Guanghao Zhang commented on HBASE-20589:

{quote}What's the expected behavior ?
There should be Aborting log or Killing log about RS but the unit test doesn't 
do it.

You only run the ut once and passed? Try more times?

> 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]
