Also, I don't think it needs to be a blocker. All the patch does is reduce the timeout, users should be able to do that by themselves.

I am not sure going as low as 5 seconds is acceptable for store operations. [~xgong] - would it be possible to run a reasonably heavy workload (1000s of apps) with 5s default, and see if that causes any issues? Otherwise, I could set one of our RM HA clusters to use 5s timeout and see what happens.

I think this is the reason why it takes so long for standby RM transits to active. To address this issue, we can simply change the default value to 5s, which is used in HDFS. Also, we can adjust this config by setting yarn.resourcemanager.zk-timeout-ms in YARN-SITE.XML Yarn standby RM taking long to transition to active --- Key: YARN-1878 URL: https://issues.apache.org/jira/browse/YARN-1878 Project: Hadoop YARN Issue Type: Bug Affects Versions: 2.4.0 Reporter: Arpit Gupta Assignee: Xuan Gong In our HA tests we are noticing that some times it can take upto 10s for the standby RM to transition to active. -- This message was sent by Atlassian JIRA (v6.2#6252)
