> MR-279: Need to retrieve shuffle port number on ApplicationMaster restart
> -------------------------------------------------------------------------

> Key: MAPREDUCE-2666
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2666
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Robert Joseph Evans
> Assignee: Jonathan Eagles
> Priority: Blocker
> Fix For: 0.23.0

> MAPREDUCE-2652 allows ShuffleHandler to return the port it is operating on.
> In the case of an ApplicationMaster crash where it needs to be restarted that
> information is lost. We either need to re-query it from each of the
> NodeManagers or to persist it to the JobHistory logs and retrieve it again.
> The job history logs is probably the simpler solution.
