> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: Sandeep Katta
> Assignee: Apache Spark
> Priority: Major

> Below code works fine before spark3, running on spark3 throwsÂ
> java.lang.ArrayIndexOutOfBoundsException
> {code:java}
> val inputPath = "/Users/xyz/data/testcaseInsensitivity"
> val output_path = "/Users/xyz/output"
> spark.range(10).write.format("parquet").save(inputPath)
> def process_row(microBatch: DataFrame, batchId: Long): Unit = {
> val df = microBatch.select($"ID".alias("other")) // Doesn't work
> df.write.format("parquet").mode("append").save(output_path)
> }
> val schema = new StructType().add("id", LongType)
> val stream_df =
> spark.readStream.schema(schema).format("parquet").load(inputPath)
> stream_df.writeStream.trigger(Trigger.Once).foreachBatch(process_row _)
> .start().awaitTermination()
> {code}
> Stack Trace:
> {code:java}
