Description
Spark cluster can reproduce, local can't:
1. Start a spark context with spark.reducer.maxReqSizeShuffleToMem=1K and spark.serializer=org.apache.spark.serializer.KryoSerializer:
$ spark-shell --conf spark.reducer.maxReqSizeShuffleToMem=1K --conf spark.serializer=org.apache.spark.serializer.KryoSerializer
2. A shuffle:
scala> sc.parallelize(0 until 3000000, 10).repartition(2001).count()
The error messages:
