Shannon, When you use TextInputFormat, the keys in your mapper will be the byte offsets into the file, and in particular the will be LongWritable. If you change your mapper to have LongWritable keys, it will all "just work".

The basic problem is that something has produced data that uses a long as an ID and your mapper is expecting an int. Have you posted your code as a patch on the jira or a git link?
