Subject Making crunch job output single file
Date Wed, 30 Oct 2013 15:05:12 GMT
Hi all,

I have a crunch job that should process a big sequence file and produce a
single csv file. I am using the "pipeline.writeTextFile(transformedRecords,
csvFilePath)" to write to a csv. (csvFilePath is like
"/data/csv_directory"). The larger the input sequence file is, more number
of mappers are being created and thus equivalent number of csv output files
are being created.

In classic mapreduce one could output a single file by setting the
#reducers to 1 while configuring the job. How could I achieve this with

I would really appreciate any help here.
