I'm trying to run a Map-only job using .gz input format. For testing, I
have one compressed log file in the input directory. If the file is
un-zipped, the code works fine.
Watching the jobs with .gz input via the job tracker shows that the
mapper apparently has read the correct number of records (880,000), and
it reports 195,357 map output records just as it does if the input file
is un-zipped. But it then hangs until I finally kill the job.
And ideas what I'm missing?
