Richard Ding commented on PIG-1973:
-----------------------------------
I agree that this is a better usage idiom. But the initialValue method is
invoked the first time a thread accesses the ThreadLocal variable with the get
method, so the outcomes are the same.
> UDFContext.getUDFContext has a thread race condition around it's ThreadLocal
