[jira] [Created] (YARN-1514) Utility to benchmark ZKRMStateStore#loadState for ResourceManager-HA

             Summary: Utility to benchmark ZKRMStateStore#loadState for ResourceManager-HA
                 Key: YARN-1514
                 URL: https://issues.apache.org/jira/browse/YARN-1514
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Tsuyoshi OZAWA
            Assignee: Tsuyoshi OZAWA
             Fix For: 2.4.0


ZKRMStateStore is very sensitive to ZNode-related operations as discussed in YARN-1307, YARN-1378 and so on. Especially, ZKRMStateStore#loadState is called when RM-HA cluster does failover. Therefore, its execution time impacts failover time of RM-HA.

We need utility to benchmark time execution time of ZKRMStateStore#loadStore as development tool.
