> As per *https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/csv/CSVFileFormat.scala#L119-L126)*,
> _"Since Spark 2.3, the queries from raw JSON/CSV files are disallowed when the referenced columns only include the internal corrupt record column"_
> But it's allowing while querying only the internal corrupt record column in case of *filter* operation.
> from pyspark.sql.types import *
> schema = StructType([StructField("_corrupt_record",StringType(),False),StructField("Name",StringType(),False),StructField("Colour",StringType(),True),StructField("Price",IntegerType(),True),StructField("Quantity",IntegerType(),True)])
> df = spark.read.csv("fruit.csv",schema=schema,mode="PERMISSIVE")
> df.filter(df._corrupt_record.isNotNull()).show()   // Allowed
