> A common pattern in HDFS is for multiple segment files underneath a given
> directory, representing the fragments of data. Lots of tools understand to
> automatically merge these segment files (ie hadoop fs -getmerge, pig script
> loaders). This patch does the same for the HDFS consumer, using a temporary
> local directory for the merging.
> Additionally, tools like pig and oozie understand to look for a _SUCCESS file
> in one of these directories containing segments. This file indicates that
> the segments have been completely written. This patch additionally skips the
> directory if a _SUCCESS file is not present.
