Description
Hi:
I've encountered the following NPE when storm tries to deserialize. I did not use OutputCollector concurrently in my code. The only object we are passing between bolts are a thrift object, and we have written a serializer for it. I've attached the code of serializer and please help to check whether there are any potential bugs there.
