> Filenames containing commas or semicolons cause MultipleInputs to break since these characters are used for joining and storing the path names.
> MultipleInputs stores mapreduce.input.multipleinputs.dir.formats as:
> path;inputFormatClass,path2;inputFormatClass2[, ...]
> If a filename contains one of the characters used for joining the data then getInputFormatMap and getMapperTypeMap will fail.
> Looking at FileInputFormat.addInputPath() it uses escapeString and unescapeString from StringUtils. I took the same approach for escaping in MultipleInputs.
