Arun Suresh created YARN-4270: --------------------------------- Summary: Limit application resource reservation on nodes for non-node/rack specific requests Key: YARN-4270 URL: https://issues.apache.org/jira/browse/YARN-4270 Project: Hadoop YARN Issue Type: Bug Components: fairscheduler Reporter: Arun Suresh Assignee: Arun Suresh
I has been noticed that for off-switch requests, the FairScheduler reserves resources on all nodes. This could lead to the entire cluster being unavailable for all other applications. Ideally, the reservations should be on a configurable number of nodes, default 1. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
