The current Hadoop platform has at least one issue when being used by an MR2 application; it winds up configuring the job with a single reduce task, due to https://issues.apache.org/jira/browse/MAPREDUCE-4288. So what we'd like is a new platform (which extends the HadoopPlatform). This should perhaps by default set the number of reducers to one per node, as that's information we should be able to get back from YarnClusterMetrics.
