             Summary: Improves the error message when fails to parse some json file lines in DataFrameReader
                 Key: SPARK-17374
                 URL: https://issues.apache.org/jira/browse/SPARK-17374
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Sean Zhong


Demo case:

We silently replace corrupted line with null without any error message.

{code}
import org.apache.spark.sql.types._
val corruptRecords = spark.sparkContext.parallelize("""{"a":{, b:3}""" :: Nil)
val schema = StructType(StructField("a", StringType, true) :: Nil)
val jsonDF = spark.read.schema(schema).json(corruptRecords)
scala> jsonDF.show
+----+
|   a|
+----+
|null|
+----+
{code}
