Subject [jira] [Commented] (YARN-2054) Poor defaults for YARN ZK configs for retries and retry-inteval
Date Thu, 15 May 2014 04:28:29 GMT

    [ https://issues.apache.org/jira/browse/YARN-2054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13998433#comment-13998433
] 

Jian He commented on YARN-2054:
-------------------------------

Does it make sense to link with the config HA enabled also ? If we have another RM sitting
standby, we may want to failover quickly. But if we have only one RM, and somehow ZK is unavailable,
RM will only retry for 10 seconds and shuts down.

> Currenly, we have the following default values:
> # yarn.resourcemanager.zk-num-retries - 500
> # yarn.resourcemanager.zk-retry-interval-ms - 2000
> This leads to a cumulate 1000 seconds before the RM gives up trying to connect to the
ZK.
