[jira] [Created] (MAPREDUCE-3002) Delink History Context from AppContext

Delink History Context from AppContext
--------------------------------------

                 Key: MAPREDUCE-3002
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3002
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobhistoryserver, mrv2
    Affects Versions: 0.24.0
            Reporter: Robert Joseph Evans


Currently the JobHistory Server has a HistoryContext that pretends to be a Map Reduce ApplicationMaster's AppContext so that UI pages can be shared between the two.  This is not ideal because the UIs have already diverged a lot, and we have to translate the native History Server's data into implementations of Job to provide the same interface.
