Ivan Sadikov updated SPARK-40468:
---------------------------------
Description:
I have found that depending on the name of the corrupt record in CSV, the field
is populated incorrectly. Here is an example:
{code:java}
1,a > /tmp/file.csv
===
val df = spark.read
.schema("c1 int, c2 string, x string, _corrupt_record string")
.csv("file:/tmp/file.csv")
.withColumn("x", lit("A"))
Returns:
+---+---+---+---------------+
|c1 |c2 |x |_corrupt_record|
+---+---+---+---------------+
|1 |a |A |1,a |
+---+---+---+---------------+{code}
> Column pruning is not handled correctly in CSV when _corrupt_record is used
> ---------------------------------------------------------------------------
