Arun Suresh updated YARN-4270: ------------------------------ Attachment: YARN-4270.3.patch Previous test case failure was spurious. Updating Patch anyway: # Added one more testcase to verify behavior for rack local reservations # Fixed checkstyle warnings [~kasha], do you want to give it a quick rev ? > 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 > Attachments: YARN-4270.1.patch, YARN-4270.2.patch, YARN-4270.3.patch > > > I has been noticed that for off-switch requests, the FairScheduler reserves > resources on all nodes.
