BELUGA BEHR created HDFS-9596: --------------------------------- Summary: Remove "Shuffle" Method From DFSUtil Key: HDFS-9596 URL: https://issues.apache.org/jira/browse/HDFS-9596 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 2.7.1 Reporter: BELUGA BEHR Priority: Trivial Attachments: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
