> Split locations - at least for FileInputSplits - are generally tied to the
> location on HDFS where the split resides.
> There are situations in which this location is not necessarily the best
> location to process this split.
> e.g.
> Clusters where compute and storage are separate.
> Systems which cache data - cache affinity is more important.
> Providing an alternate list of preferred locations allows grouping to the
> preferred locations, instead of always grouping based on the locations
> specified in the split.
