xsys updated SPARK-40637: ------------------------- Description: h3. Describe the bug When we store a BINARY value (e.g. {{BigInt("1").toByteArray)}} / {{{}X'01'{}}}) either via {{spark-shell or spark-sql, and then read it from Spark-shell, it}} outputs {{{}[01]{}}}. However, it does not encode correctly via {{{}spark-sql{}}}. h3. To Reproduce On Spark 3.2.1 (commit {{{}4f25b3f712{}}}), using {{{}spark-shell{}}}: {code:java} $SPARK_HOME/bin/spark-shell{code} Execute the following: {code:java} scala> val rdd = sc.parallelize(Seq(Row(BigInt("1").toByteArray))) rdd: org.apache.spark.rdd.RDD[org.apache.spark.sql.Row] = ParallelCollectionRDD[356] at parallelize at <console>:28 scala> val schema = new StructType().add(StructField("c1", BinaryType, true)) schema: org.apache.spark.sql.types.StructType = StructType(StructField(c1,BinaryType,true)) scala> val df = spark.createDataFrame(rdd, schema) df: org.apache.spark.sql.DataFrame = [c1: binary] scala> df.show(false) +----+ |c1 | +----+ |[01]| +----+ scala> df.write.mode("overwrite").format("orc").saveAsTable("binary_vals") scala> spark.sql("select * from binary_vals;").show(false) +----+ |c1 | +----+ |[01]| +----+{code} We can see the output using "spark.sql" in spark-shell.
