------------------------------------
Assignee: Apache Spark
> 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
> Assignee: Apache Spark
> Priority: Major
>
> 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);
> at com.esotericsoftware.kryo.Kryo.getRegistration(Kryo.java:488)
