-------------------------------
Summary: Fail a failed Pig script quicker
Key: PIG-3254
URL: https://issues.apache.org/jira/browse/PIG-3254
Project: Pig
Issue Type: Improvement
Reporter: Daniel Dai
Fix For: 0.12
Credit to [~asitecn]. Currently Pig could launch several mapreduce job
simultaneously. When one mapreduce job fail, we need to wait for simultaneous
mapreduce job finish. In addition, we could potentially launch additional jobs
which is doomed to fail. However, this is unnecessary in some cases:
* If "stop.on.failure==true", we can kill parallel jobs, and fail the whole
script
* If "stop.on.failure==false", and no "store" could success, we can also kill
parallel jobs, and fail the whole script
Consider simultaneous jobs may take a long time to finish, this could
significantly improve the turn around in some cases.
