Dims, Not that I know of; I believe that Cassandra works fine with OpenJDK. See [1] and [2].
From time to time, there have been questions about the supported JDK for Cassandra, a recent one (just that I happen to remember this) tries to make the case that you must use Sun/Oracle JDK. This is not a requirement by any means. See [3]. To the best of my knowledge, OpenJDK is sufficient. -amrith [1] http://wiki.apache.org/cassandra/GettingStarted [2] http://docs.datastax.com/en/cassandra/2.2/cassandra/install/installDeb.html [3] http://stackoverflow.com/questions/21487354/does-latest-cassandra-support-openjdk From: Davanum Srinivas [mailto:[email protected]] Sent: Saturday, October 10, 2015 8:54 PM To: OpenStack Development Mailing List (not for usage questions) <[email protected]> Subject: Re: [openstack-dev] Scheduler proposal Not implying cassandra is the right option.

AFAIK, cassandra works well with OpenJDK. Can you please elaborate what you concerns are for #1?

Does cassandra use some features of the JVM that the openJDK version doesn't support? Something else? -Josh Thomas Goirand wrote: On 10/07/2015 07:36 PM, Ed Leafe wrote: Several months ago I proposed an experiment [0] to see if switching the data model for the Nova scheduler to use Cassandra as the backend would be a significant improvement as opposed to the current design This is probably right. I don't know, I'm not an expert in Nova, or its scheduler. However, to make it possible for us (ie: downstream distributions and/or OpenStack users) to use Cassandra, you have to solve one of the below issues: 1/ Cassandra developers upstream should start caring about OpenJDK, and make sure that it is also a good platform for it. They should stop caring only about the Oracle JVM. ... or ... 2/ Oracle should make its JVM free software. As there is no hope for any of the above, Cassandra is a no-go for downstream distributions. So, by all means, propose a new back-end, implement it, profit. But that back-end cannot be Cassandra the way it is now.
