Tsuyoshi OZAWA commented on YARN-1514:
--------------------------------------
Rough design:
1. Launch ZKRMStateStore and initialize ZooKeeper.
2. Creating znodes based on given option.
3. Run loadState() and show how much time it takes.
> Utility to benchmark ZKRMStateStore#loadState for ResourceManager-HA

> 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.
