[jira] [Updated] (SPARK-38285) ClassCastException: GenericArrayData cannot be cast to InternalRow
[ https://issues.apache.org/jira/browse/SPARK-38285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alessandro Bacchini updated SPARK-38285:
----------------------------------------
Description:
The following code with Spark 3.2.1 raises an exception:
{code:python}
import pyspark.sql.functions as F
from pyspark.sql.types import StructType, StructField, ArrayType, StringType
t = StructType([
StructField('o',
ArrayType(
StructType([
StructField('s', StringType(), False),
StructField('b', ArrayType(
StructType([
StructField('e', StringType(), False)
]),
True),
False)
]),
True),
False)])
value = {
"o": [
{
"s": "string1",
"b": [
{
"e": "string2"
},
{
"e": "string3"
}
]
},
{
"s": "string4",
"b": [
{
"e": "string5"
},
{
"e": "string6"
},
{
"e": "string7"
}
]
}
]
}
df = (
spark.createDataFrame([value], schema=t)
.select(F.explode("o").alias("eo"))
.select("eo.b.e")
)
df.show()
{code}
The exception message is:

{code}
I am using Spark 3.2.1, but I don't know if even Spark 3.3.0 is affected.
Please note that the issue seems to be related to SPARK-37577: I am using the same DataFrame schema, but this time I have populated it with non empty value.
I think that this is bug because with the following configuration it works as expected:
{code:python}
spark.conf.set("spark.sql.optimizer.expression.nestedPruning.enabled", False)
spark.conf.set("spark.sql.optimizer.nestedSchemaPruning.enabled", False)
{code}
