>  We encountered PIG-4649 with HCatStorer where it was hardcoding the part file name and not honoring mapreduce.output.basename. If there were two vertex groups writing to same output directory one was overwriting another as file names were same without part-v000-o000 prefix. Tez should fail the job in that case instead of silently losing data.
