-------------------------------

Thanks for the patch, Dave! Would you have time to add a flag for opt-in? (I know it's holidays season. So it's totally fine if you're busy. I'm happy to finish that part for you.)

> The AvroInputFormat class explicitly checks each input path for a '.avro' extension. 
> If only some of the input paths have the correct extension, the remainder are silently ignored and not included in the job. However, if none of the input paths have the extension, the job will continue and succeed even though no map tasks are allocated, and no work is done.
> This only happens using the old mapred API. The new mapreduce API version will happily read files regardless of extension. 
> Is the check necessary?
