Description
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.
