> The default FileInputFormat::getSplits method does not include zero-byte input files
in FileSplit[]. Applications that assume the minimum number of maps to be at least number
of input files can get bitten by this, as well as  applications that use -reducer NONE to
produce number of partitions that are equal to input partitions.
