Konstantinos Karanasos commented on YARN-2882:
----------------------------------------------

bq. Thanks for picking this up, Inigo Goiri. Hope that is okay with Konstantinos Karanasos.
That is fine with me (and I do appreciate the help), given the urgency for unblocking YARN-1011,
but let's coordinate better next time.

I would have liked to review the patch before we pushed it to trunk.
I am travelling at the moment and have limited connectivity, but will give it a look tomorrow.

> This JIRA introduces the notion of container types.
> We propose two initial types of containers: guaranteed-start and queueable containers.
> Guaranteed-start are the existing containers, which are allocated by the central RM and
are instantaneously started, once allocated.
> Queueable is a new type of container, which allows containers to be queued in the NM,
thus their execution may be arbitrarily delayed.
