Subject Hadoop cluster configuration
Date Tue, 27 Nov 2012 20:15:32 GMT
Hi Hadoop user community,

I am trying to setup my first Hadoop cluster and I've found most of the instructions a little
confusing. I've seen how-to's that say "core-site.xml" should have hdfs://localhost:8020 and
others say hdfs://localhost:50030". Which one is correct? Can someone please help with the
configuration?

I'm starting out with a 4 machine cluster on CentOS VM's. I've created the 2 masters and 2
slaves.

My Masters are:
JobTracker
NameNode

My Slaves are:
TrackTracker
DataNode

Finally, how can I test to verify that the masters are talking to the slaves and vice-versa?
Thanks in advance.
