I did try the single node setup, it is worst than the cluster set= up regarding the instructions. You are supposed to already have a near work= ing system as far as I understand the instructions. It is assumed the HDFS = is already setup and working properly. Try to find the instructions to setu= p HDFS for version 2.2.0 and you will end up with a lot of inappropriate in= structions about previous version (some properties were renamed).

It may appear hard at people to say this is toxic, but it is. The= first place a newcomer will go is setup a single node. This will be his st= arting point and he will be left with a bunch of a priori and no clue.

To go back to my very problem at this point:

Hi Daniel,

first of all, before posting to a mailing list, take a deep breath and
let your frustrations out. Then write the email. Using words like
"crappy", "toxicware", "nightmare" are not going to help you getting
useful responses.

While I agree that the docs can be confusing, we should try to stay
constructive. You haven't  mentioned which documentation you are
using. I found the cluster tutorial sufficient to get me started:
http://hadoop.apache.org/docs/s= table/hadoop-project-dist/hadoop-common/ClusterSetup.html

If you are looking for an easy way to spin up a small cluster with
hadoop 2.2, try the hadoop2 branch of this vagrant setup:

https://github.com/fs111/vagrant-hadoop-cluster/tree/hadoop= 2
