Insert/Update ( Merge statement) using full join

Hi guys, 
I need to merge incremental data file to master data  file in pig ver 0.12.
It is set of either new records or changes to existing records based on that I should update the existing rows in a file or add the new ones.
I join the two files with full outer join and getting difference. 
What is simple approach. Please advice.
Thanks,VK
