Subject [jira] [Commented] (YARN-3334) [Event Producers] NM TimelineClient life cycle handling and container metrics posting to new timeline service.
Date Wed, 01 Apr 2015 17:44:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-3334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14391059#comment-14391059
] 

Zhijie Shen commented on YARN-3334:
-----------------------------------

bq. For using ContainerEntity to replace TimelineEntity, there is a bug that UnrecognizedPropertyException
will get thrown in serialize/deserialize "children" element when consuming it as base class
(TimelineEntity). 

I probably know the problem. I'll fix it seperately: YARN-3431. Let's leave this issue in
this jira.

> After YARN-3039, we have service discovery mechanism to pass app-collector service address
among collectors, NMs and RM. In this JIRA, we will handle service address setting for TimelineClients
in NodeManager, and put container metrics to the backend storage.
