Subject [jira] [Commented] (CASSANDRA-9581) pig-tests spend time waiting on /dev/random for SecureRandom
Date Thu, 11 Jun 2015 22:22:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14582604#comment-14582604
] 

Joshua McKenzie commented on CASSANDRA-9581:
--------------------------------------------

What are the implications for Windows?
{code:title=proposed build.xml changes}
        <!-- The first time SecureRandom initializes can be slow if it blocks on /dev/random
-->
        <jvmarg value="-Djava.security.egd=file:/dev/urandom" />
{code}

No /dev/urandom on the platform so I'm assuming this won't end well.

> We don't need secure random numbers (for unit tests) so waiting for entropy doesn't make
much sense. Luckily Java makes it easy to point to /dev/urandom for entropy. It also transparently
handles it correctly on Windows.
