Zac Hopkinson updated MAPREDUCE-6596:
-------------------------------------
Description:
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.
