---------------------------------------
Summary: Improvements for error reporting
Key: SYSTEMML-1147
URL: https://issues.apache.org/jira/browse/SYSTEMML-1147
Project: SystemML
Issue Type: Epic
Components: Compiler, Documentation
Reporter: Felix Schüler
Error reporting is in many cases not very user friendly.
For example, wrong indexing in a user-defined function leads to long
stack-traces that only contain information about the instructions and finally
end with an IndexOutOfBoundsException.
In general, the reported instructions are not very helpful because they also
only contain renamed variables (e.g. _Var42) that don't correspond to anything
in the DML script.
This epic is to track error messages that could use some improvements.
Here is an Example of a case that is not very helpful:
