+1.  It is helpful for the metrics to have unique names.

> The names used for map, reduce, and shuffle metrics currently overlap:
> Map metrics:
>   input_bytes 
>   input_records 
>   output_bytes 
>   output_records 
> Recduce metrics:
>    input_records 
>    output_records 
> Shuffle metrics:
>    input_bytes 
> I propose that the metric names be unique:
>   map_input_bytes 
>   map_input_records 
>   map_output_bytes 
>   map_output_records 
>   shuffle_input_bytes 
>   reduce_input_records 
>   reduce_output_records
