Carlo Curino commented on YARN-5215:
------------------------------------
Bar proper synching with YARN-1011 and YARN-5202 efforts and polishing the
patch to include tests and conf switches,
I am very supportive of this effort. It seems a rather simple change that can
deal with a broad set of issues when YARN
is not the only thing running on a set of machines. The fact that you have
been running this for a while is also reassuring.
Were those prod clusters? Scale?
Please provide a cleaned-up version of the patch, and comment on [~jlowe]
comment.
[~jlowe] would you be ok with this going in? Can you build upon it for the work
you are doing or is it horribly incompatible?

> Currently YARN runs containers in the servers assuming that they own all the
> resources. The proposal is to use the utilization information in the node and
> the containers to estimate how much is consumed by external processes and
> schedule based on this estimation.
