Robert Kanter created HADOOP-14246:
--------------------------------------

             Summary: Authentication Tokens should use SecureRandom instead of Random \
and 256 bit secrets  Key: HADOOP-14246
                 URL: https://issues.apache.org/jira/browse/HADOOP-14246
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 2.9.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter


{{RandomSignerSecretProvider}} and {{ZKSignerSecretProvider}} currently use a \
{{long}} generated by {{Random}} (which is then converted to a {{String}} and is 160 \
bits) for secrets.  

We should improve this to use 256 bit secrets generated by {{SecureRandom}}.
