wenbang commented on HBASE-22923:
---------------------------------
When the nodes of system table group are all in the list of exclude nodes, can we assign the system table across the group?

> {code:java}
> master.AssignmentManager: Failed assignment of hbase:meta,,1.1588230740 to localhost,1,1, trying to assign elsewhere instead; try=1 of 10 java.io.IOException: Call to localhost/127.0.0.1:1 failed on local exception: org.apache.hadoop.hbase.ipc.FailedServerException: This server is in the failed servers list: localhost/127.0.0.1:1
> {code}
> hbase group list:
> HBASE_META group（hbase:meta and other system tables）
> default group
> 1.Down grade all servers in HBASE_META first
> 2.higher version servers is in default
> 3.hbase:meta assigned to localhost
> For system table, we assign them to a server with highest version.
