Hi developers: I have set spark.kryo.registrationRequired=true, but an exception occured: java.lang.IllegalArgumentException: Class is not registered: org.apache.spark.internal.io.FileCommitProtocol$TaskCommitMessage when I run the program.
I tried to register it manually by kryo.register() and Sparkconf.registerKryoClasses, but it still not work. The related JIRA is SPARK-21569. And SPARK-10251, SPARK-6497 are may the same problem I think. Be grateful if someone can help me.. Best Regards, Lijun Cao
