kryo encountered unregistered class ID: 15

I'm sorry if I shouldn't leave a question here, but I really cannot figure this out. I'm trying to test some very simple hive script, but this error kept coming up:

Exception in thread "main" org.apache.hive.com.esotericsoftware.kryo.KryoException: Encountered unregistered class ID: 15

This only happens when the hive script involves 'load' operation. So it is good to create table, but when comes to load data this just pop up. Here is the log:

Which I don't see much help either. I'm sorry again if this is not the right place to ask help, but any idea of solving this is so welcomed. If you need any info about my setting or script please just let me know. Thanks in advance!
