Joydeep Sen Sarma commented on HIVE-1463:
-----------------------------------------

> Issue Type: Improvement
> Reporter: Joydeep Sen Sarma

> Hive's output files are named like this:
> attempt_201006221843_431854_r_000000_0
> out of all of this goop - only one character '0' would have sufficed. we
> should fix this. This would help environments with namenode memory
