Subject [jira] [Commented] (YARN-3630) YARN should suggest a heartbeat interval for applications
Date Fri, 15 May 2015 17:17:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-3630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14545807#comment-14545807

Vinod Kumar Vavilapalli commented on YARN-3630:
-----------------------------------------------

NodeManagers already get a target heartbeat interval via responses. We haven't seen a real-life
need yet for adaptive tuning, so we haven't done that. The same should be done here, for now,
we should just send the target interval across and tune it later.

> It seems currently applications - for example Spark - are not adaptive to RM regarding
heartbeat intervals. RM should be able to suggest a desired heartbeat interval to applications.
