Gordon Wang commented on YARN-2808:
-----------------------------------
setting yarn.resourcemanager.max-completed-applications to 0 is not a solution
from my view.
RM could cache completed app generic info, so that it is easy for user to check
the job status. And more, user could find the job info in RM's web UI, then,
redirect to history-server/timeline-server for more app detail info.
I think YARN-1794 is similar, but not the same.

And was intending to fix by "modifing YarnClientImpl.getContainers(). If the
size of containers is 0. We can get it from timeline."
{quote}
I am afraid this fix is only for YARN-2808 case. But generally speaking, since
RM does not cache completed container info, if a app is running, both the size
of running containers and the size of completed container could be larger than
0. So, one possible fix is that pulling the container info both from RM and
timeline-server regardless of the state of app attempt.
