Guanghao Zhang created HBASE-20589:
--------------------------------------
Summary: Don't need to assign meta to a new RS when standby master
become active
Key: HBASE-20589
URL: https://issues.apache.org/jira/browse/HBASE-20589
Project: HBase
Issue Type: Bug
Reporter: Guanghao Zhang
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]
