@liujiayi771 do you know if collect_set is not expected to work with complex
types if the value is null? Example, this works with Spark, but doesn't work
when Gluten is enabled:
import org.apache.spark.sql.functions._
val jsonStr =
"""{"txn":{"appId":"txnId","version":0,"lastUpdated":null}}"""
val jsonSchema = StructType(Seq(StructField("txn",
StructType(Seq(StructField("appId",StringType,true),StructField("lastUpdated",LongType,true),StructField("version",LongType,true))),true
)))
val df =
spark.read.schema(jsonSchema).json(Seq(jsonStr).toDS).select(collect_set(col("txn")))
df.head
