> The implementation of {{RDD.isEmpty()}} fails if there is empty partitions.
> It was introduce by https://github.com/apache/spark/pull/4074
> Example:
> {code}
> sc.parallelize(Seq(), 1).isEmpty()
> {code}
> The above code throws an exception like this:
> {code}
> org.apache.spark.SparkDriverExecutionException: Execution error
