-----------------------------------------
Assignee: Hossein Falaki
> Improve SparkR error messages for DataFrame API
> -----------------------------------------------
>
> Key: SPARK-8742
> URL: https://issues.apache.org/jira/browse/SPARK-8742
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Affects Versions: 1.4.1
> Reporter: Hossein Falaki
> Assignee: Hossein Falaki
> Priority: Blocker
> Fix For: 1.5.0
>
>
> Currently all DataFrame API errors result in following generic error:
> {code}
> Error: returnStatus == 0 is not TRUE
> {code}
> 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.
