Ben Slater updated CASSANDRA-12744: ----------------------------------- Attachment: CASSANDRA_12744_SeedManager_changes-trunk.patch > Randomness of stress distributions is not good > ---------------------------------------------- > > Key: CASSANDRA-12744 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12744 > Project: Cassandra > Issue Type: Bug > Components: Tools > Reporter: T Jake Luciani > Assignee: Ben Slater > Priority: Minor > Labels: stress > Fix For: 4.0 > > Attachments: CASSANDRA_12744_SeedManager_changes-trunk.patch > > > The randomness of our distributions is pretty bad. We are using the > JDKRandomGenerator() but in testing of uniform(1..3) we see for 100 > iterations it's only outputting 3. If you bump it to 10k it hits all 3 > values. > I made a change to just use the default commons math random generator and now > see all 3 values for n=10 -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
