----------------------------------
Thanks [~kasha] / [~haibo.chen] for the proposal.
I just left some comments in YARN-6808:
https://issues.apache.org/jira/browse/YARN-6808?focusedCommentId=16087782&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16087782
It may related to this feature as well, so could you please take a look when
you have time?
I think it might be better to move some JIRAs to a new umbrella: "improve using
opportunistic container for normal use cases". YARN-1014/YARN-6674 like I
suggested in YARN-6808.
Thoughts?

> Currently RM allocates containers and assumes resources allocated are
> utilized.
> RM can, and should, get to a point where it measures utilization of allocated
> containers and, if appropriate, allocate more (speculative?) containers.
