Subject Re: Can not follow Single Node Setup example.
Date Thu, 27 Jun 2013 18:11:44 GMT
I just started learning hadoop. And I followed
http://hadoop.apache.org/docs/r1.1.2/single_node_setup.html. Is
DataNode mentioned in this document? Do you have a list of working
step by step instructions so that I run hadoop without anything
previously installed? Thanks.
