Junping Du commented on MAPREDUCE-4900: --------------------------------------- Binglin, Thanks for the work. I see your code also include list slots of each node. Can we separate this out from this jira and replaced with backport YARN-40 (including: listClusterNodes and printNodeStatus)? > Dynamic configuration for task slots on TT > ------------------------------------------ > > Key: MAPREDUCE-4900 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4900 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: resourcemanager, tasktracker > Affects Versions: 1.1.1 > Reporter: Junping Du > Assignee: Binglin Chang > Attachments: MAPREDUCE-4900-demo.patch, > MAPREDUCE-4900-demo-with-JMX.patch, MAPREDUCE-4900-demo-with-JMX.v2.patch > > > The current Hadoop MRV1 resource management logic assumes per node slot > number is static during the lifetime of the TT process. Allowing run-time > configuration on per node slot will give us finer granularity of resource > elasticity. This allows Hadoop workloads to coexist with other workloads on > the same hardware efficiently, whether or not the environment is virtualized. > For more background or design details of this effort, please refer proposal > in HADOOP-9165. -- This message is automatically generated by JIRA.
