You could hook up http://hadoop.apache.org/common/docs/r0.20.1/api/org/apache/hadoop/mapreduce/lib/output/TextOutputFormat.html to a map that emit tsv lines (use the tsv escaping lib du jour to make sure tabs are properly escaped or just search and replace tabs in source yourself if not corrupting).
