Devaraj K commented on YARN-2301:
---------------------------------
Here it is trying allocate this memory for heap size. And we need to leave the
remaing memory for launching the Child container java process, native memory,
etc.
As [~jianhe] mentioned, RM removes the completed containers or containers for
completed attempts. I think there would not be much useful by providing
completed appAttemptId for -list param and displaying some message or empty
result.
I would think of giving appId option for -list (i.e. -list <appId>) and print
the containers running for current application attempt.

> While running yarn container -list <Application Attempt ID> command, some
> observations:
> 1) the scheme (e.g. http/https ) before LOG-URL is missing
> 2) the start-time is printed as milli seconds (e.g. 1405540544844). Better to
> print as time format.
> 3) finish-time is 0 if container is not yet finished. May be "N/A"
> 4) May have an option to run as yarn container -list <appId> OR yarn
> application -list-containers <appId> also.
> As attempt Id is not shown on console, this is easier for user to just copy
> the appId and run it, may also be useful for container-preserving AM
> restart.
