Subject [jira] [Commented] (YARN-6753) Expose more ContainerImpl states from NM in ContainerStateProto
Date Fri, 30 Jun 2017 23:46:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6753?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16070876#comment-16070876
] 

Jian He commented on YARN-6753:
-------------------------------

Yep, I kinda prefer working on the existing class.  Since the container state is also used
by RM for its own logic e.g RMNodeImpl#handleContainerStatus, similar kind of mapping needs
to be done there also. 

On a related note, while working on YARN-1503, I also thought to expose the state of whether
localization failed or succeeded.  But there I need a more sophisticated localization status
per resource, though we probably also need a limit to limit the number resources object returned,
otherwise, it could make the getContainerStatus heavy.

> The current NM protobuf definition exposes a subset of the NM internal state via ContainerStateProto.
> We are currently building tools that can use of more fine grain state like LOCALIZING,
LOCALIZED, EXIT_WITH_FAILURES etc.
> The proposal is to add more internal states in the API.
> I'm not sure if this is considered an Incompatible change or not
