> Components: PySpark

>Reporter: Jeff Zhang
>Priority: Minor

> When I use DataFrame#explain(), I found the output is a little different from
> scala API. Here's one example.

> == Physical Plan ==// this line is removed in pyspark API
> Scan
> JSONRelation[file:/Users/hadoop/github/spark/examples/src/main/resources/people.json][age#0L,name#1]
> {noformat}
> After looking at the code, I found that pyspark will print the output by
> itself rather than delegate it to spark-sql. This cause the difference
> between scala api and python api. I think both python api and scala api try
> to print it to standard out, so the python api can be delegated to scala api.
> Here's some api I found that can be delegated to scala api directly:
> * printSchema()
> * explain()
> * show()
