[jira] [Created] (HADOOP-11891) OsSecureRandom should lazily fill its reservoir

Arun Suresh created HADOOP-11891:
------------------------------------

             Summary: OsSecureRandom should lazily fill its reservoir
                 Key: HADOOP-11891
                 URL: https://issues.apache.org/jira/browse/HADOOP-11891
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Arun Suresh
            Assignee: Arun Suresh
             Fix For: 2.7.1


The {{OsSecureRandom}} class that is initialized by on the the {{CryptoCodec}} implementations eagerly fills its reservoir of random bits. This will result in too many file descriptors being opened simply and is not really required if the client already has a random IV and key needed for decryption.
