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.
