There is something similar in
src/examples/org/apache/hadoop/examples/Grep.java.  Instead of
outputting pure word counts, it counts occurrences of a regex.  Switch
the first map reduce job with the one in WordCount.java in the same
directory and you're golden.

Howdy,

Can anyone point me to an example of chaining MapReduce operations
(e.g., Word Count followed by inverting the "Word" and "Count"
columns so one wound up with the list sorted by count rather than by
word)?

Thanks,

David
