Running Cassandra on FreeBSD

Hi,

we downloaded the latest release and tried to run it on a FreeBSD 11
machine which resultet in a JVM crash. Here is the output:

Is BSD not supported by Cassandra or are we missing something else here?

thanks for the information. I guess we'll choose a platform from the
list then.

Jens,

I don't believe it is supported on FreeBSD - I would recommend  you stick
to the list here:
https://docs.datastax.com/en/landing_page/doc/landing_page/supportedPlatforms.html
. Also, I would suggest using Oracle JDK.

Regards,

Johnny

Re: Running Cassandra on FreeBSD

Posted by "Jeronimo de A. Barros" <je...@gmail.com>.
Jens,

Al Tobey's Cassandra 2.1 tuning guide has excellents infos about running
Cassandra. Apparently he uses Arch Linux and we've been using Slackware
Linux in a 12 node cluster (2 DCs 6/6) for the last 3 years with no
problems.

https://tobert.github.io/pages/als-cassandra-21-tuning-guide.html

You just need a modern Linux distro scrapped from any services that could
compromise I/O and CPUs performance and memory (hence, we choose Slackware).

Regards,

Jero
