Description

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.
