---------------------------------

Hi [~asuresh]. I think I am unable to assign it to myself too, there is no more 'Assign to
me' link.

>    Affects Versions: 2.3.0
>         Environment: 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08)

> YARN-2022 have fixed the similar issue related to CapacityScheduler.
> However, FairScheduler still suffer, preempting AM while other normal containers running
out there.
> I think we should take the same approach, avoid AM being preempted unless there is no
container running other than AM.
