[jira] [Created] (SPARK-3656) IllegalArgumentException when I using
sort-based shuffle
yangping wu created SPARK-3656:
----------------------------------
Summary: IllegalArgumentException when I using sort-based shuffle
Key: SPARK-3656
URL: https://issues.apache.org/jira/browse/SPARK-3656
Project: Spark
Issue Type: Bug
Components: Shuffle
Affects Versions: 1.1.0
Reporter: yangping wu
The code work fine in hash-based shuffle.
{code}
sc.textFile("file:///export1/spark/zookeeper.out").flatMap(l => l.split(" ")).map(w=>(w,1)).reduceByKey(_ + _).collect
{code}
But when I test the program using sort-based shuffle,the program encounters an error：
{code}
scala> sc.textFile("file:///export1/spark/zookeeper.out").flatMap(l => l.split(" ")).map(w=>(w,1)).reduceByKey(_ + _).collect
org.apache.spark.SparkException: Job aborted due to stage failure: Task 22 in stage 1.0 failed 1 times, most recent failure: Lost task 22.0 in stage 1.0 (TID 22, localhost): java.lang.IllegalArgumentException: Comparison method violates its general contract!
