Subject [jira] [Commented] (YARN-3034) implement RM starting its ATS writer
Date Tue, 10 Feb 2015 20:01:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-3034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14314797#comment-14314797
] 

Sangjin Lee commented on YARN-3034:
-----------------------------------

Some feedback on the patch...

(1) this creates a dependency from RM to the timeline service; perhaps it is unavoidable...
(2) RMTimelineAggregator.java
- we need the license
- annotate with @Private and @Unstable
- line. 31: nit; spacing

(3) SystemMetricsPublisher.java
- instead of replacing the use of the existing ATS, I think we need to have both (the existing
ATS calls as well as the new calls); we will need a global config that enables/disables the
next gen timeline service
