>                 Key: BEAM-673
>                 URL: https://issues.apache.org/jira/browse/BEAM-673
>             Project: Beam
>          Issue Type: Bug
>          Components: runner-spark

> In some distributed filesystems, such as HDFS, we should be able to hint to Spark the
preferred locations of splits.
> Here is an example of how Spark does that for Hadoop RDDs:
> https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/rdd/NewHadoopRDD.scala#L252
> *Note: in case of 1-to-1 mapping of Read operation (e.g. TextIO) direct translation should
still be preferred, but this is pending HDFS support for Beam anyway.*
