Hi All,
I'm trying to get some hands-on on the Map Reduce programming.
I downloaded the code examples from Hadoop-The definitive guide, 3rd edition
and build it using Maven:
mvn package -DskipTests -Dhadoop.distro=apache-2
Next I imported the maven projects into Eclipse. Using Eclipse now I can
develop my own Map Reduce jobs.
Bu how do I test\run the job locally using the "Local Job Runner"?
The book excerpt says:
Now we can run this application against some local files. Hadoop comes with a
local
job runner, a cut-down version of the MapReduce execution engine for running
Map-
Reduce jobs in a single JVM. It’s designed for testing, and is very convenient
for use in
an IDE, since you can run it in a debugger to step through the code in your
mapper and
reducer.
Do I also need to install Hadoop locally on Windows for that?
Thanks,
-RR
