Wangda Tan commented on YARN-2882:
----------------------------------
[~asuresh], [~kasha],
Since ContainerType is not in any of the releases, theoretically we can still
change ContainerType to a boolean to indicate if it is an AM container or not.
And then we can reuse the ContainerType to describe if it is a
speculative/opportunistic container or not.
Thoughts?
> Add ExecutionType to denote if a container execution is GUARANTEED or
> QUEUEABLE

> 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.
