> SerDeUtil Pair RDD to python conversion doesn't accept empty RDDs
> -----------------------------------------------------------------

> Key: SPARK-5441
> URL: https://issues.apache.org/jira/browse/SPARK-5441
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 1.1.1, 1.2.0
> Reporter: Michael Nazario
> Assignee: Michael Nazario
> Labels: backport-needed
> Fix For: 1.3.0, 1.2.2
>
>
> SerDeUtil.pairRDDToPython and SerDeUtil.pythonToPairRDD rely on rdd.first()
> which throws an exception if the RDD is empty. We should be able to handle
> the empty RDD case because this doesn't prevent a valid RDD from being
> created.
