             Summary: CSV data source treats empty string as null no matter what nullValue option is
                 Key: SPARK-17916
                 URL: https://issues.apache.org/jira/browse/SPARK-17916
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.1
            Reporter: Hossein Falaki


When user configures {{nullValue}} in CSV data source, in addition to those values, all empty string values are also converted to null.

{code}
data:
col1,col2
1,"-"
2,""
{code}

{code}
spark.read.format("csv").option("nullValue", "-")
{code}

We will find a null in both rows.
