Hi All,
I am interested in contributing to the Cassandra project. As a first step, I
have setup my development environment based on the instructions over here:
http://wiki.apache.org/cassandra/RunningCassandraInEclipse
My run/debug configuration is using the following class as the main class:
org.apache.cassandra.service.CassandraDaemon
Following is the output on the console on starting cassandra:
