Binglin Chang updated MAPREDUCE-4900: ------------------------------------- Target Version/s: 1.2.0 Affects Version/s: 1.1.1 > 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 > > 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.
