Michael Nazario created SPARK-5441:
--------------------------------------
Summary: 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: 1.2.0, 1.1.1
Reporter: Michael Nazario
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.
