seems querying _corrupt_record is not working. I tried it today and not allowing me to query with the column name.cust_df.filter("_corrupt_record is not null"). AnalysisException: Since Spark 2.3, the queries from raw JSON/CSV files are disallowed when the referenced columns only include the internal corrupt record column (named _corrupt_record by default). For example: spark.read.schema(schema).csv(file).filter($"_corrupt_record".isNotNull).count() and spark.read.schema(schema).csv(file).select("_corrupt_record").show(). Instead, you can cache or save the parsed results and then send the same query. For example, val df = spark.read.schema(schema).csv(file).cache() and then df.filter($"_corrupt_record".isNotNull).count().
cust_df.select("_corrupt_record").show() is working but not allowing is null or not null. cust_df.select("_corrupt_record is null").show(). let me know if this is working for you. thank you.

cust_df.cache()
Cache dataframe and it's won't raise exception
@@TRRaveendra Yes I did, even after that also not allowing to write a query on _corrupt_record is null or not null.
seems badRecordsPath is only the solution.
Woah what a explanation
are any such mode options available while reading parquet files?
cust_df.select("_corrupt_record").show() is working but not allowing is null or not null. cust_df.select("_corrupt_record is null").show(). let me know if this is working for you. thank you.
Why do we write inferschema= true
InferSchema =True Creating datatypes based on data.
Header = True creating columns from file first line
Hi pls share ur contact details I am looking for python, pyspark, databricks training
