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 inĀ 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.
