Junping Du created MAPREDUCE-4900: ------------------------------------- Summary: 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 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.
