Summary: Kryo serialization issue with push-based shuffle
Key: SPARK-48043
URL: https://issues.apache.org/jira/browse/SPARK-48043
Project: Spark
Issue Type: Bug
Components: Shuffle
Affects Versions: 3.4.1
Environment: AWS EMR 6.14 (Spark 3.4.1)
Reporter: Romain Ardiet
I'm running a spark job on AWS EMR. I wanted to test the new push-based shuffle
introduced in Spark 3.2 but it's failing with a kryo exception when I'm
enabling it.
The issue seems happening when Executor starts, on
KryoSerializerInstance.getAutoReset() check:
{code:java}
24/04/24 15:36:22 ERROR YarnCoarseGrainedExecutorBackend: Executor self-exiting
due to : Unable to create executor due to Failed to register classes with Kryo
