Summary: Throttle Localization for Opportunistic Containers in the NM
Key: YARN-7547
URL: https://issues.apache.org/jira/browse/YARN-7547
Project: Hadoop YARN
Issue Type: Bug
Reporter: Arun Suresh
Assignee: kartheek muthyala
Currently, Localization is performed before the container is queued on the NM. It is possible
that a barrage of Opportunsitic containers can prevent Guaranteed containers from starting.
This can be avoided by throttling Localization Requests for opportunistic containers - for
eg. if the number of Queued containers is > x, then don't start localization for new Opp
containers.
