> Currently we return a null String array to the MR framework to use a random
> node for MR job assignment.
> class: org.apache.hadoop.hbase.mapred.tableSplit
> function getLocations()
> We should be able to query the meta now for the current host name of the
> server hosting the region in question.
> This will help with scaling as there will be less cross server communication
> removing bandwidth as a bottleneck.
> The side effect of fixing this will help from overloading region servers with
> lots of MR clients all pulling from the same region server while theres work
> local for them to do.
