> Key: PHOENIX-3600
> URL: https://issues.apache.org/jira/browse/PHOENIX-3600
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 4.8.0

>
> 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.
