Wang Yan commented on MAPREDUCE-7148:
-------------------------------------
[~jlowe] Thanks a lot for your review comment! I have reflected them in the
latest patch(MAPREDUCE-7148.009.patch). As for LimitedPrivate, I left as it is
as [[email protected]] gave some reasonable explanations. I think the failed
tests are not related to the patch because the tests also failed in the truck.
Could you please take another look? Thanks in advance!

> 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 .
