Description

Currently all DataFrame API errors result in following generic error:

Error: returnStatus == 0 is not TRUE

This is because invokeJava in backend.R does not inspect error messages. For most use cases it is critical to return better error messages. Initially, we can return the stack trace from the JVM. In future we can inspect the errors and translate them to human-readable error messages.
