                 Key: MAPREDUCE-1044
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1044
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: dhruba borthakur
            Assignee: Dmytro Molkov


We have multiple map-reduce clusters that provide different service and support levels for their users. We have seen that utilization of hardware resources are not optimized if we have a static partition of existing hardware resources into these separate MR clusters. It would be nice to have a automatic way to move nodes from one MR cluster to another based on load characteristics and configured policies. This JIRA will discuss some of the ideas and possible implementations of those ideas.
