    Description

      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.
