Map/reduce stops working with comma separated input paths
---------------------------------------------------------

                 Key: HADOOP-3162
                 URL: https://issues.apache.org/jira/browse/HADOOP-3162

When a job is given a comma separated input file list, FileInputFormat class throws an exception,
complaining the input is invalid:
