[jira] [Created] (SPARK-8742) Improve SparkR error messages for
DataFrame API
Hossein Falaki created SPARK-8742:
-------------------------------------
Summary: 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
Priority: Blocker
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.
