> 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.
