Hairong Kuang commented on HADOOP-4746:
---------------------------------------
The down side of doing this in FileOutputFormat#checkOutputSpecs() is that if a
user writes its own customized OutputFormat, the user might forget to normalize
the output directory in checkOutputSpecs(). Otherwise I am OK with this
suggestion.
> Job output directory should be normalized
