             Summary: Usability improvements for Python DSL
                 Key: SYSTEMML-917
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-917
             Project: SystemML
          Issue Type: Improvement
            Reporter: Arvind Surve


Based on current experience of Python DSL, which we understand its in very early and experimental state, we need to have following addressed as a part of Python DSL support (assume similar will be applicable for Scala DSL)

1. Generate descriptive error message point to exact error instead of multiple stack traces.
2. Line # and/or statement causing error from the script.
3. Explain to reflect HOPS etc properly.
    Last time we observed that within a for loop it generates HOPS for every iteration, instead of once.
