------------------------------------------
I feel it is enough to use Console?
{code}
val outputStream = new java.io.ByteArrayOutputStream()
val out = new java.io.PrintStream(outputStream, true);
Console.withOut(out) { Seq(1, 2, 3, 4).toDS.show() }
scala> outputStream.toString

> Add a DataFrame.show() with argument for output PrintStream

> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.5.2
> Reporter: Dean Wampler
> Priority: Minor
>
> It would be nice to send the output of DataFrame.show(...) to a different
> output stream than stdout, including just capturing the string itself. This
> is useful, e.g., for testing. Actually, it would be sufficient and perhaps
> better to just make DataFrame.showString a public method,
