Suchintak Patnaik created SPARK-29621:
-----------------------------------------
Summary: Querying internal corrupt record column should not be
allowed in filter operation
Key: SPARK-29621
URL: https://issues.apache.org/jira/browse/SPARK-29621
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 2.3.0
Reporter: Suchintak Patnaik
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
