      Description

      As JD and Elliot mentioned, turning off ZKAssign logging can improve AM performance a lot. During the testing, I also noticed that: after all regions are already opened, master UI still shows lots of regions in transition. It is because AM hasn't finished the ZK event processing yet.

      Changing the logging level from debug to trace will improve AM performance. With HBASE-6611, I think AM is getting stable and reliable. I hope we don't need to see these logging any more.

      The logging is still available after turning trace logging level on for AM and ZKAssign class.
