Wangda Tan commented on YARN-1197: ---------------------------------- Hi [~mding], I just completed clean up of sub JIRAs. I think some of them are too detailed. For example, it will be very hard to split works in FiCaSchedulerNode/FiCaSchedulerApp with changes of LeafQueue/ParentQueue. Following are JIRAs after cleanup: *API:* YARN-1449, API in NM side to support change container resource. YARN-1502, API changes in RM side to support change contaienr resource. *Client:* YARN-1509, AMRMClient YARN-1510, NMClient *NM implementation* YARN-1643, ContainerMonitor changes in NM *RM implementation* YARN-1646, Support change container resource in RM. YARN-1651, CapacityScheduler side changes. I unassigned myself from many of these JIRAs, but I still plan to implement changes in RM/CS side. For other JIRAs, please feel free to take. > 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: YARN-1197_Design.pdf, 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)
