> If you have more than one input, InputSizeReducerEstimator.getTotalInputFileSize can
return incorrect value if one of the loader returns \-1 and is not file based (eg- hbase).
This causes incorrect reducer estimation and problems in auto.local mode.
> If size of input is not found in for any of the inputs, we should bail out with return
value of -1.
