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 > -------------------------------------------------------------------- > > 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: 2.5.0 > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
