Subject [jira] [Created] (SPARK-19709) CSV datasource fails to read empty file
Date Thu, 23 Feb 2017 10:42:45 GMT
Hyukjin Kwon created SPARK-19709:
------------------------------------

             Summary: CSV datasource fails to read empty file
                 Key: SPARK-19709
                 URL: https://issues.apache.org/jira/browse/SPARK-19709
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Hyukjin Kwon
            Priority: Minor


I just {{touch a}} and then ran the codes below:

{code}
scala> spark.read.csv("a")
java.util.NoSuchElementException: next on empty iterator
	at scala.collection.Iterator$$anon$2.next(Iterator.scala:39)
	at scala.collection.Iterator$$anon$2.next(Iterator.scala:37)
	at scala.collection.IndexedSeqLike$Elements.next(IndexedSeqLike.
{code}

It seems we should produce an empty dataframe consistently with `spark.read.json("a")`.
