Subject [jira] [Commented] (YARN-1577) Unmanaged AM is broken because of YARN-1493
Date Thu, 09 Jan 2014 05:32:51 GMT

    [ https://issues.apache.org/jira/browse/YARN-1577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13866335#comment-13866335
] 

Zhijie Shen commented on YARN-1577:
-----------------------------------

bq. We may need to introduce an attempt state report that client can rely on to query the
attempt state and choose to launch the unmanaged AM.

When we worked on AHS, we've added the report for application attempt (YARN-978), and client
is able to query the info of application attempt, including the state via RPC interface. However,
we only implemented the AHS part. When AHS is brought to trunk, we can move on to add the
implementation in ClientRMSerivce as well

> Today unmanaged AM client is waiting for app state to be Accepted to launch the AM. This
is broken since we changed in YARN-1493 to start the attempt after the application is Accepted.
We may need to introduce an attempt state report that client can rely on to query the attempt
state and choose to launch the unmanaged AM.
