Subject RE: cannot start Cassandra on Windows7
Date Mon, 25 Mar 2013 10:03:28 GMT
I always run Cassandra (from 0.9 to latest 1.2.3) on Win7 machine without any issue with default
configuration settings. The only thing I've changed in cassandra.yaml is cluster_name. I also
recommend to add an additional JVM flag -Dfile.encoding=UTF-8 in cassandra.bat and cassandra-cli.bat
and always run cassandra.bat without '-f'. If you want to run Cassandra as service on Windows
machine you should use some service wrapper, for example http://wrapper.tanukisoftware.com

It's there:

http://www.datastax.com/docs/1.2/cluster_architecture/cluster_planning#node-init-config

It's a long document.... You need to look at the cassandra.yaml and cassandra-env.sh and make
sure you understand the settings there. 

By the way, did datastax just face lift their document web site? It looks nice.

Thanks, Jabbar, Victor,
Yes, after I made similar changes I was able to start Cassandra too. 
Would be nice if these instructions were included with the main Cassandra documentation/WIKI
:)

Thanks!

cassandra.yaml and log4j-server.properties need modifying.
