Major Description
The following test case would cause a "max iterations reached" error, i.e., an infinite loop in the optimizer.
test("optimization infinite loop") { withTempDir { dir => val path = dir.getCanonicalPath import testImplicits._ Seq((3, "a")).toDF("id", "value").write.format("parquet").mode("overwrite").save(path) import org.apache.spark.sql.functions.udf val filterIt = udf((value: Int) => value > 0).asNondeterministic spark.read.load(path) .where(filterIt('id)) .where('id < 0) .select('id) .collect } }
