Apache Spark commented on SPARK-37728: -------------------------------------- User 'yym1995' has created a pull request for this issue: https://github.com/apache/spark/pull/35002 > reading nested columns with ORC vectorized reader can cause > ArrayIndexOutOfBoundsException > ------------------------------------------------------------------------------------------ > > Key: SPARK-37728 > URL: https://issues.apache.org/jira/browse/SPARK-37728 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.0.3, 3.1.2, 3.2.0 > Reporter: Yimin Yang > Priority: Major > > When spark.sql.orc.enableNestedColumnVectorizedReader is set to true, reading > nested columns of ORC files can cause ArrayIndexOutOfBoundsException. Here is > a simple reproduction: > 1) create an ORC file which contains records of type Array<Array<String>>: > {code:java} > ./bin/spark-shell {code} > {code:java} > case class Item(record: Array[Array[String]]) > val data = new Array[Array[Array[String]]](100) > for (i <- 0 to 99) { > val temp = new Array[Array[String]](50) > for (j <- 0 to 49) { > temp(j) = new Array[String](1000) > for (k <- 0 to 999) { > temp(j)(k) = k.toString > } > } > data(i) = temp > } > val rdd = spark.sparkContext.parallelize(data, 1) > val df = rdd.map(x => Item(x)).toDF > df.write.orc("file:///home/user_name/data") {code} > > 2) read the orc with spark.sql.orc.enableNestedColumnVectorizedReader=true > {code:java} > ./bin/spark-shell --conf spark.sql.orc.enableVectorizedReader=true --conf > spark.sql.codegen.wholeStage=true --conf > spark.sql.orc.enableNestedColumnVectorizedReader=true --conf > spark.sql.orc.columnarReaderBatchSize=4096 {code} > {code:java} > val df = spark.read.orc("file:///home/user_name/data") > df.show(100) {code} > > Then Spark threw ArrayIndexOutOfBoundsException: > Driver stacktrace: > at >
