Summary: 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.
