Subject [jira] [Commented] (YARN-3116) [Collector wireup] We need an assured way to determine if a container is an AM container on NM
Date Tue, 30 Jun 2015 00:25:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14606723#comment-14606723
] 

Giovanni Matteo Fumarola commented on YARN-3116:
------------------------------------------------

Thanks [~subru] and [~zjshen] for the offline discussion and the feedback. As agreed upon,
I am uploading an updated patch that:
   * Adds a flag to indicate if a container is AM or not in _ContainerTokenIdentifier_.
   * Adds a flag to indicate if a container is AM or not in _ContainerContext_. We require
the flag in both ContainerInitializationContext and ContainerTerminationContext for YARN-2884.

> In YARN-3030, to start the per-app aggregator only for a started AM container,  we need
to determine if the container is an AM container or not from the context in NM (we can do
it on RM). This information is missing, such that we worked around to considered the container
with ID "xxxx_01" as the AM container. Unfortunately, this is neither necessary or sufficient
condition. We need to have a way to determine if a container is an AM container on NM. We
can add flag to the container object or create an API to do the judgement. Perhaps the distributed
AM information may also be useful to YARN-2877.
