Jules Testard updated BEAM-7756:
--------------------------------
Issue Type: Improvement (was: Bug)
> Stack trace not useful in SQL dsl for Java
> ------------------------------------------
>
> Key: BEAM-7756
> URL: https://issues.apache.org/jira/browse/BEAM-7756
> Project: Beam
> Issue Type: Improvement
> Components: dsl-sql
> Reporter: Jules Testard
> Priority: Major
>
> I am testing Apache Beam to be used in our company's environment. I could be
> missing something, but it seems the stack tracing is very limited, in
> particular when using the SQL dsl available for the Beam Java SDK. This makes
> troubleshooting more difficult.
>
> One minimal example shows it very well:
> [https://github.com/jtestard/beam-sql-stack-trace] (the pom.xml in this repo
> should detail all dependencies used, the JDK used is Java 8). This GitHub
> repo gives attempts perform two back-to-back SQL transforms, the first of
> which contains a mismatch between input and output schema. The stack trace,
> however, gives little indication of the problem and does not trace to which
> transform the problem originated in:
