[Roshrini]

@idealboy Can you provide the script you are trying to run to better understand the issue you are facing? Are you calling scala APIs from java in your example?

@nswamy Can you add label-
UnclearError/Doc

[lanking520]

I think you are trying to call Python API for Java right? We are currently working on the Java support. I recommend you to start with Scala library that already existed as you can import that to Java directly.

Since we do not have information to reproduce, I will close this issue. Please feel free to create a new Issue if there is still a problem.
