Subject [jira] [Commented] (HADOOP-10734) Implementation of true secure random with high performance using hardware random number generator.
Date Sat, 12 Jul 2014 00:56:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14059556#comment-14059556
] 

Colin Patrick McCabe commented on HADOOP-10734:
-----------------------------------------------

OK, I looked at this again, and Random implements Serializable (for some reason?)  So we probably
should have this to avoid generating warnings.  So +1 for the patch as-is.

Thanks, all.  I will commit shortly and let you guys file whatever follow-ups make sense

> This JIRA is to implement Secure random using JNI to OpenSSL, and implementation should
be thread-safe.
> Utilize RdRand to return random numbers from hardware random number generator. It's TRNG(True
Random Number generators) having much higher performance than {{java.security.SecureRandom}}.
