[TOREE-395] disable cell result output
This issue - discussed in
[TOREE-395](https://issues.apache.org/jira/browse/TOREE-395) (and somewhat in
[TOREE-380](https://issues.apache.org/jira/browse/TOREE-380)) - essentially
takes the appropriate portion of PR #104 and delivers it here. This change
makes the scala interpreter behave like other interpreters (and kernels) by not
issuing the cell results to the console (where it is typically captured by the
Jupyter logging) and could contain sensitive information.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/kevin-bates/incubator-toree

[TOREE-395] disable cell result output
----
> Provide a way to disable automatic printing of results in Toree Scala
> ---------------------------------------------------------------------
>
> Key: TOREE-395
> URL: https://issues.apache.org/jira/browse/TOREE-395
> Project: TOREE
> Issue Type: Improvement
> Affects Versions: 0.2.0
> Reporter: Kun Liu
>
> Scala REPL supports a flag, ":silent" to enable/disable automatic printing of
> results (those messages begin with "res"). This is also supported in Spark
> shell. But for Toree Scala kernel, this flag is not supported. Thus the
> result of a cell would be always printed.
> But if there is any logging mechanism, the results would be recorded in a log
> file, while this may not be desirable. For instance, a user may not want any
> sensitive data logged when running "dataRDD.take(5)" in a cell.
> Also found the possible source codes for this:
> https://github.com/apache/incubator-toree/blob/master/scala-interpreter/src/main/scala/org/apache/toree/kernel/interpreter/scala/ScalaInterpreter.scala
> There are three methods with silent: Boolean = false as parameter.
