Daniel Dai commented on PIG-1884:
---------------------------------
In general, I think calling LoadFunc.setLocation before launching hadoop job is
beneficial. This gives user a hook to setup UDFContext properly. There could be
some minor backward compatibility issues, but our document clearly state it
will be called multiple times in both frontend and backend. So I think it is Ok.
To fix this issue, we can simply remove "throw UnsupportedOperationException"
in ReadToEndLoader, which seems unnecessary.
> Change ReadToEndLoader.setLocation not throw UnsupportedOperationException
