I'll update the patch. > 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: 2.7.0 > > Attachments: YARN-1514.1.patch, YARN-1514.2.patch, YARN-1514.3.patch, YARN-1514.4.patch, YARN-1514.4.patch, YARN-1514.5.patch, YARN-1514.5.patch, YARN-1514.6.patch, YARN-1514.wip-2.patch, YARN-1514.wip.patch > > > 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 (v6.3.4#6332)
