Subject [jira] [Commented] (YARN-3046) [Event producers] Implement MapReduce AM writing some MR metrics to ATS
Date Mon, 20 Apr 2015 16:27:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-3046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14503133#comment-14503133
] 

Zhijie Shen commented on YARN-3046:
-----------------------------------

Another issue:

Shall we do nullcheck in TimelineEvent. Theoretically, we shouldn't block users from putting
null value, though in this case we may want to avoid it. However, we can do it at the HistoryEvent
side.

> Per design in YARN-2928, select a handful of MR metrics (e.g. HDFS bytes written) and
have the MR AM write the framework-specific metrics to ATS.
