> Remove "Shuffle" Method From DFSUtil
> ------------------------------------
>
> Key: HDFS-9596
> URL: https://issues.apache.org/jira/browse/HDFS-9596
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Trivial
> Attachments: HDFS-9596.2.patch, HDFS-9596.3.patch, HDFS-9596.4.patch,
> HDFS-9596.5.patch, HDFS-9596.6.patch, HDFS-9596.7.patch, HDFS-9596.7.patch,
> HDFS-9596.7.patch, Shuffle.HDFS-9596.patch
>
>
> DFSUtil contains a "shuffle" routine that shuffles arrays. With a little
> wrapping, Java Collections class can shuffle. This code is superfluous and
> undocumented. The method returns an array, though it does not specify if it
> returns the same array or a new, copy, array of shuffled items.
> It is only used in one place, so it is better to simply remove and substitute
> this implementation with the java Collections implementation.
