---------------------------------------------

             Summary: MapReduceHelper should sort respective of the number of reduce tasks
                 Key: TINKERPOP3-842
                 URL: https://issues.apache.org/jira/browse/TINKERPOP3-842
             Project: TinkerPop 3
          Issue Type: Improvement
          Components: hadoop
            Reporter: Marko A. Rodriguez
            Assignee: Marko A. Rodriguez
             Fix For: 3.1.0-incubating


In Hadoop2, sorting reduce output is more complex than simply setting an {{IdentityReducer}}. Right now, to get sorted map and reduce output, the number of reduce tasks needs to be set to 1. This is not a good long term solution. Figure out how to make it work for an arbitrary number of reducers.
