      Description

      In java, SecureRandom is slow and is pseudo random bytes.
      In HADOOP-10734, we implement true secure random using hardware random number generator, it has high performance about 22x speedup.
      If the server doesn't support rdrand, use java SecureRandom as fallback.

          +1 for doing this. We need to wait until the branch merge if we want to target this on trunk directly.
