> The core MapReduce classes {{org.apache.phoenix.mapreduce.PhoenixInputSplit}} and {{org.apache.phoenix.mapreduce.PhoenixInputFormat}}
don't provide region size or location information, leaving the execution engine (MR, Spark,
etc.) to randomly assign splits to nodes.
> Interestingly, the phoenix-hive module has reimplemented these classes, including the
node-aware functionality. We should port a subset of those changes back to the core code so
that other engines can make use of them.
