Subject [jira] [Commented] (YARN-974) RMContainer should collection more useful information to be recorded
Date Fri, 26 Jul 2013 17:13:49 GMT

Omkar Vinit Joshi commented on YARN-974:
----------------------------------------

bq. Thanks for the remind. Since the history information is recorded and used after the completion
of an application, IMHO, we just need the after run log. Please correct me if I'm wrong.
So you are saying we won't get any info till application finishes? I thought we will get this
information once container starts but it may or may not have finished or application may or
may not have finished. So we will have transitions like.. nothing -> present locally on
node manager -> present on remote hdfs.

> To record the history of a container, users may be also interested in the following information:
> 1. Start Time
> 2. Stop Time
> 3. Diagnostic Information
> 4. URL to the Log File
> 5. Actually Allocated Resource
> 6. Actually Assigned Node
> These should be remembered during the RMContainer's life cycle.
