-RE: Make job output be a comma separated file
Botelho, Andrew 2013-07-18, 18:02
I believe that mapred.textoutputformat.separator is from the old API, but now the field is mapreduce.output.textoutputformat.separator in the new API.
So I ran this code in my driver class, but it is making no difference:
Configuration conf = new Configuration();
Am I changing the field right?

You can pass change the default keyValueSeparator of the output format from a "\t" to a "," by
setting the following property mapred.textoutputformat.separator to Configuration of the job.
You will face difficulties if this output is an input to another job as you wouldn't know what part of the row data is a key and what is the value.

What is the best way to make the output of my Hadoop job be comma separated? Basically, how can I have the keys and values be separated by a comma?
My keys are Text objects, and some of them have actual commas within the field. Will this matter?
