----------------------------------
Summary: Using KryoSerializer and setting registrationRequired
true can lead job failed
Key: SPARK-25100
URL: https://issues.apache.org/jira/browse/SPARK-25100
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.3.1
Reporter: deshanxiao
When spark.serializer is org.apache.spark.serializer.KryoSerializer and
spark.kryo.registrationRequired is true in SparkCOnf. I invoked
saveAsNewAPIHadoopDataset to store data in hdfs. The job will fail because the
class TaskCommitMessage hasn't be registered.
{code:java}
java.lang.IllegalArgumentException: Class is not registered:
org.apache.spark.internal.io.FileCommitProtocol$TaskCommitMessage
Note: To register this class use:
kryo.register(org.apache.spark.internal.io.FileCommitProtocol$TaskCommitMessage.class);
