If you actually want to shade cassandra the following works.
You just need to add the maven bundle plugin to this, you'll have a complete
cassandra bundle that contains all the necessary bits and pieces.

I have wrapped an external library ( Cassandra - Hector Client ) as a bundle ,

How did you go about making it a bundle?
Is there any other way I can explicitly make one bundle aware of other ?
You need to make sure two things happen. Your Cassandra bundle exports the
correct packages and your other bundle imports the correct packages.
Just in case if anyone has see it , this is the error
Caused by: java.lang. ClassNotFoundException: org.apache.thrift.transport.

appreciate any help

Hi Chris,
Thanks for the input. Karaf has a beautiful wrapper for external library
osgi:install wrap:mvn:Group/Artifact/version does a quick and easy install.
Have you checked the imports/exports of your bundles? From the Karaf console
"headers<bundle-id>".
regards,
Ramesh
Thanks Johan, I will try the same for both cassandra and hector client.
regards,
Ramesh
