kryo throws Encountered unregistered class exception

[hjh <ap...@163.com>]

Hi,
     I use kryo to serialize and deserialize class defined by myself(all 
registered in kryo), but when I run my topology, I got this exception as 
shown below. I googled for this issue it seems to be kryo version that 
caused this problem. I checked the version of the kryo I use, it is 
2.21. How can I solve this problem? By the way I excluded nearly all 
kryo dependencies in the project. However this is a collaborated 
project, just not sure if it will be affected by other modules. And also 
I tested kryo alone, it works fine. Can anyone provide a "clean" 
solution to this problem? Any suggestion will be helpful thank you very 
much!!
