Weiwei Yang resolved YARN-4165. ------------------------------- Resolution: Invalid > An outstanding container request makes all nodes to be reserved causing all > jobs pending > ---------------------------------------------------------------------------------------- > > Key: YARN-4165 > URL: https://issues.apache.org/jira/browse/YARN-4165 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacity scheduler, resourcemanager, scheduler > Affects Versions: 2.7.1 > Reporter: Weiwei Yang > Assignee: Weiwei Yang > > We have a long running service in YARN, it has an outstanding container > request that YARN cannot satisfy (require more memory that nodemanager can > supply). Then YARN reserves all nodes for this application, when I submit > other jobs (require relative small memory that nodemanager can supply), all > jobs are pending because YARN skips scheduling containers on the nodes that > have been reserved. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
