For additional check that I mentioned. The following code shows that Spark 
users does not need to add take(1). ds.rdd.take(1).isEmpty is redundant.


[RDD.scala](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/rdd/RDD.scala)
 
`def isEmpty(): Boolean = withScope {
partitions.length == 0 || take(1).length == 0
}`

@rxin, checking empty is likely to be a common process in every ETL batch 
job. I think it is the right place to provide that functionality. When a basic 
function is missing already supposed to be provided, people spend unnecessary 
time for searching and creating their own creative functions. It does not help 
us develop clean code or business value neither. I added one of the 
stack-overflow discussions at SPARK-23627 for your reference. I also would like 
to confirm rdd.isEmpty is optimized internally following up this issue.

So the API looks useful, but I don't know if this is the right 
implementation. How important is it to add this? It seems like the value is not 
super high either.
