Subject Re: Main method not found in class org.apache.cassandra.service.CassandraDaemon

Vivek,

The location of CassandraDaemon changed between versions.  (from
org.apache.cassandra.thrift to org.apache.cassandra.service)

It is likely that the start scripts are picking up the old version on the
classpath, which results in the main method not being found.

Do you have CASSANDRA_HOME set?  I believe the start scripts will use that.
 Perhaps you have that set and pointed to the older 1.1.X version?
