[jira] [Created] (ZEPPELIN-3672) spark interpreter: Java output (to the console) is lost

DG created ZEPPELIN-3672:
----------------------------

             Summary: spark interpreter:  Java output (to the console) is lost
                 Key: ZEPPELIN-3672
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3672
             Project: Zeppelin
          Issue Type: Bug
          Components: Interpreters
    Affects Versions: 0.9.0
            Reporter: DG


It could be a trivial configuration issue (in which case apologies!!  A Zeppelin newbie here), or perhaps it is a bug, in any event the output is unexpected

 

 
{noformat}
%spark

System.out.println("hello from java")
println("hello from scala")
{noformat}
only "scala" is shown in the output, whilst Java is lost.  Similarly, all output from Java through Log4j is lost as well.

The issue is critical, since we cannot currently show iteration log (convergence, and other metrics) from a Spark-Java app.

Ideas?

Thank you beforehand!!
