Carlo Curino commented on YARN-1990:
------------------------------------
YARN-1051 is committed. If someone tries it and finds issues with the
time-to-allocation, we can re-hash this. Otherwise we can just close this in a
while.
> Track time-to-allocation for different size containers

> Key: YARN-1990
> URL: https://issues.apache.org/jira/browse/YARN-1990
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Reporter: Carlo Curino
> Assignee: Carlo Curino

> Allocation of Large Containers are notoriously problematic, as smaller
> containers can more easily grab resources.
> The proposal for this JIRA is to maintain a map of container sizes, and
> time-to-allocation, that can be used as:
> * general insight on cluster behavior,
> * to inform the reservation-system, and allows us to "account for delays" in
> allocation, so that the user reservation is respected regardless the size of
> containers requested.
