Hi ,



I want my reducer output to be dumped into a csv file, How can that be
done?

Or can we convert part-000 to a csv ?



hadoop fs -cat /some/where/on/hdfs/job-output/part-* >
TheCombinedResultOfTheJob.csv

This doesn't work I get only the first column in csv file.



Regards,

Shreya Pal

    Shreya,

    Assuming your file output was already CSV (i.e. your job wrote it as so),
    you can get a merged file via:

    hadoop dfs -getmerge /some/dir/of/multiple/files mergedfile.csv
