             Summary: Users schema with non-nullable properties is overidden with true
                 Key: SPARK-18270
                 URL: https://issues.apache.org/jira/browse/SPARK-18270
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.1
            Reporter: Jork Zijlstra


Users schema with non-nullable properties is overidden with true in CSVRelation.csvParser.

The schema that is given to the CSVRelation.csvParser(schema: StructType) isnt the version that is user specifies.
All nullable option are set to true

Specifying the schema:
StructType(Array(
  StructField("id", IntegerType, nullable = false),
  StructField("underlyingId", IntegerType, true)
))

Read the data:
sparkSession.read
    .schema(sourceSchema)
    .option("header", "false")
    .option("delimiter", """\t""")
    .csv(files(dates): _*)
    .rdd

Actual Result: 
schema inside csvParser contains only nullable = true values.
