---------------------------------
Summary: Limit number of reservations for an app
Key: YARN-3691
URL: https://issues.apache.org/jira/browse/YARN-3691
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler
Reporter: Arun Suresh
Currently, It is possible to reserve resource for an app on all nodes. Limiting
this to possibly just a number of nodes (or a ratio of the total cluster size)
would improve utilization of the cluster and will reduce the possibility of
starving other apps.
