Subject [jira] [Commented] (YARN-3034) [Collector wireup] Implement RM starting its timeline collector
Date Mon, 23 Mar 2015 18:35:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-3034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14376349#comment-14376349

Naganarasimha G R commented on YARN-3034:
-----------------------------------------

Thanks for your comments [~zjshen]
bq. RM_SYSTEM_METRICS_PUBLISHER_ENABLED -> SYSTEM_METRICS_PUBLISHER_ENABLED is an incompatible
change. :
This i incorporated based on [~vinodkv]'s [comment|https://issues.apache.org/jira/browse/YARN-3034?focusedCommentId=14360797&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14360797],
And also i have added old keys as part of {{addDeprecatedKeys}}, so i think its not an incompatible
change. Please provide your opinion on the same.

bq. RMTimelineCollector doesn't need to be exposed to RM and it's context. It seems to be
enough to construct it inside SystemMetricsPublisher only.
IIUC  SystemMetricsPublisher.publish*Event methods can determine which version of ATS to publish
and can post it accordingly ?
