Error opening zip file or JAR manifest missing : /usr/share/dse/cassandra/lib/jamm-0.3.0.jar

Error

The error shown in output.log is:

Tomcat: Logging to /data_disk/tomcat_logs 
Error opening zip file or JAR manifest missing : /usr/share/dse/cassandra/lib/jamm-0.3.0.jar 
Error occurred during initialization of VM 
agent library failed to init: instrument 

Solution

The referenced jar file is missing in the location specified or the file is there, but the version is different. You can either change the version in cassandra-env.sh by editing the filename, or you can update the path with the version specified in cassandra-env.sh. Preferably, choosing either option that updates to latest build version.
