You want the KeyValueTextInputFormat instead of TextInputFormat. It has its default separator as tab, so you do not need to configure the delimiter.
However, in case you do have to change the delimiter byte, use the config: "mapreduce.input.keyvaluelinerecordreader.key.value.separator" For more, see http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/mapred/KeyValueTextInputFormat.html On Sat, Jul 14, 2012 at 6:00 AM, Jay Vyas <jayunit...@gmail.com> wrote: > Hi guys : Whats the idiomatic way to iterate through the k/v pairs in a > text file ? been playing with almost everything everything with > SequenceFiles and almost forgot :) > > my text output actually has tabs in it...
