Subject Re: How to test/run Hadoop after build the code
Date Tue, 06 Dec 2011 10:21:44 GMT
Check the single node and cluster setup documentation for Hadoop

http://hadoop.apache.org/common/docs/r0.23.0/ - for the new MR engine (0.23
release)
http://hadoop.apache.org/common/docs/r0.20.205.0/ - for the old MR engine
(non 0.23 release)

Here are some other tutorials for running 0.23 release.
