OutputCollector: key and value are separated by tab, why?
Hi,
that is what I observe, that in the resulting text file the two are
separated by a tab. Can I change it, is it in any way configurable?
Thank you,
Mark

Assuming you're using TextOutputFormat, you can set it in your job
configuration during setup:
conf.set("mapred.textoutputformat.separator", ",");
would make the separator a comma.

They are separated by a tab, so that the KeyValueLineRecordReader can read
the output.
In hadoop 19, the paramter mapred.textoutputformat.separator can be set to
an arbitrary string which will be used as the separator for
TextOutputFormat.
