Eli Collins commented on HDFS-2335:

You can remove the imports of SecureRandom from the various users of DFSUtil#getSecureRandom.
Otherwise looks great.

> Jira for giving DataNodeCluster and NNStorage the same treatment as HDFS-1835. They're
not truly cryptographic uses as well. We should also factor this out to a utility method,
seems like the three uses are slightly different, eg one uses DFSUtil.getRandom and the other
creates a new Random object.
