Thanks for your comment! I like the idea of creating a general exception in 
hadoop-common. This is more straightforward to solve our problem. I will create 
the patch.

> We are running hive jobs with a DFS quota limitation per job(3TB). If a job 
> hits DFS quota limitation, the task that hit it will fail and there will be a 
> few task reties before the job actually fails. The retry is not very helpful 
> because the job will always fail anyway. In some worse cases, we have a job 
> which has a single reduce task writing more than 3TB to HDFS over 20 hours, 
> the reduce task exceeds the quota limitation and retries 4 times until the 
> job fails in the end thus consuming a lot of unnecessary resource. This 
> ticket aims at providing the feature to let a job fail fast when it writes 
> too much data to the DFS and exceeds the DFS quota limitation. The fast fail 
> feature is introduced in MAPREDUCE-7022 and MAPREDUCE-6489 .
