> MAP_INPUT_BYTES and MAP_OUTPUT_BYTES will be computed using the difference between FileSystem
> counters before and after each next(K,V) and collect/write op.
> In case compression is being used, these counters will represent the compressed data sizes. The uncompressed size will
> not be available.
> This is not a direct back-port of 5710. (Counters will be computed in MapTask instead of in individual RecordReaders).
> 0.20.100 ->
>    New API -> MAP_INPUT_BYTES will be computed using this method
>    Old API -> MAP_INPUT_BYTES will remain unchanged.
> 0.23 ->
>    New API -> MAP_INPUT_BYTES will be computed using this method
>    Old API -> MAP_INPUT_BYTES likely to use this method
