Subject [jira] [Commented] (YARN-309) Make RM provide heartbeat interval to NM
Date Wed, 09 Jan 2013 03:02:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13547576#comment-13547576
] 

Bikas Saha commented on YARN-309:
---------------------------------

I see the config being really a minimum value and not the default. ie. heartbeat interval
can be increased under load but RM will try to come back to the minimum heartbeat interval
for responsiveness. With that understanding, it may make sense to have it in a config when
cluster-size/workload/other-factors make it impossible for the code to achieve a consistent
1 second response time under normal working conditions.
