Error : NoClassDefFoundError: org/apache/cassandra/service/CassandraDaemon

[Vishanth Balasubramaniam <vi...@wso2.com>]

Hi,

I am relatively new to Cassandra and getting this following error when I
run Cassandra.

root@instance-00000001:/opt/cassandra/bin# cassandra
root@instance-00000001:/opt/cassandra/bin# Exception in thread "main"
java.lang.NoClassDefFoundError: org/apache/cassandra/service/CassandraDaemon
Caused by: java.lang.ClassNotFoundException:
org.apache.cassandra.service.CassandraDaemon
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class:
org.apache.cassandra.service.CassandraDaemon.  Program will exit.

I tried cassandra, cassandra -f, cassandra -f start, which all prompted me
the same issue.

I believe this could be because of incorrect Classpath, I would like to
know how to set the Classpath correctly.

Thank you,

Judging from the /opt path, this looks like a tar install - what version?

If you look at the bin/cassandra shell script, the first thing it does 
is look for cassandra.in.sh, which is in the same bin/ directory in a 
tar install. bin/cassandra.in.sh is where the jars are added to $CLASSPATH.

If this is a git checkout, you need to build cassandra, first  ;)

This question is also not on topic for the dev list (development 
discussion for cassandra), and would better be suited to the user list 
(general discussion list for users).
