Re: Cassandra Interpreter on emr-5.20.0 gives error

[Jeff Zhang]

Do you binary version or building it from source ? It seems due to scala
version issue.

Re: How to add Cassandra Interpreter to Zeppelin on EMR?

[Xun Liu]

I don't have Cassandra in my zeppelin, so I can only help you guess where the 
problem is from the log.

From your log, These two questions should all be caused by the lack of 
dependent JAR packages that Cassandra runs. You may not be setting up the 
runtime environment for Cassandra（or scala） correctly.
You can look at the missing class according to the log, then download the JAR 
package from the class name to the `zeppelin/interpreter/Cassandra/…` directory 
and try to solve the problem.
