Apache Spark reassigned SPARK-27962:
------------------------------------
Assignee: Apache Spark
> Propagate subprocess stdout when subprocess exits with nonzero status in
> deploy.RRunner
> ---------------------------------------------------------------------------------------
>
> Key: SPARK-27962
> URL: https://issues.apache.org/jira/browse/SPARK-27962
> Project: Spark
> Issue Type: Improvement
> Components: Deploy, Spark Core
> Affects Versions: 2.4.3
> Reporter: Jeremy Liu
> Assignee: Apache Spark
> Priority: Minor
>
> When the R process launched in org.apache.spark.deploy.RRunner terminates
> with a nonzero status code, only the status code is passed on in the
> SparkUserAppException.
> Although the subprocess' stdout is continually piped to System.out, it would
> be useful for users without access to the JVM's stdout to also capture the
> last few lines of the R process and pass it along in the exception message.
