> 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.
