Tsuyoshi OZAWA commented on YARN-1514:
--------------------------------------
Attached wip version 2 patch.
1. number of applications
2. number of application attempts
3. ZK connection configuration(host:port)
4. Added YarnTestDriver to launch this perf tool from {{bin/hadoop}} command.
What a latest patch doesn't solve is dependency problem. Currently, it doesn't
include dependency on zookeeper-tests, so we'll see the following class-path
error:

[~kkambatl], can we add zookeeper-tests' jar to the result of {{mvn package}}?

> 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.
