[jira] [Created] (TEZ-696) Remove implicit copying of processor
payload to input and output
Bikas Saha created TEZ-696:
------------------------------
Summary: Remove implicit copying of processor payload to input and output
Key: TEZ-696
URL: https://issues.apache.org/jira/browse/TEZ-696
Project: Apache Tez
Issue Type: Sub-task
Reporter: Bikas Saha
In the task, the processor payload is implicitly copied to the input and output if they dont have one. While this may have been convenient in some cases, its very confusing when things dont work or when they surprisingly work. Also, its probably clearer to specify payload where appropriate so that its clear which one is for which. While writing the word count example I had to spend a lot of time debugging why my outputs had stopped working when I removed the map reduce confs from my non-MR processors.
