Jeff Zhang updated YARN-1197: ----------------------------- Assignee: (was: Jeff Zhang) > Support changing resources of an allocated container > ---------------------------------------------------- > > Key: YARN-1197 > URL: https://issues.apache.org/jira/browse/YARN-1197 > Project: Hadoop YARN > Issue Type: Task > Components: api, nodemanager, resourcemanager > Affects Versions: 2.1.0-beta > Reporter: Wangda Tan > Attachments: mapreduce-project.patch.ver.1, > tools-project.patch.ver.1, yarn-1197-scheduler-v1.pdf, yarn-1197-v2.pdf, > yarn-1197-v3.pdf, yarn-1197-v4.pdf, yarn-1197-v5.pdf, yarn-1197.pdf, > yarn-api-protocol.patch.ver.1, yarn-pb-impl.patch.ver.1, > yarn-server-common.patch.ver.1, yarn-server-nodemanager.patch.ver.1, > yarn-server-resourcemanager.patch.ver.1 > > > The current YARN resource management logic assumes resource allocated to a > container is fixed during the lifetime of it. When users want to change a > resource > of an allocated container the only way is releasing it and allocating a new > container with expected size. > Allowing run-time changing resources of an allocated container will give us > better control of resource usage in application side -- This message was sent by Atlassian JIRA (v6.3.4#6332)
