Error starting hadoop-2.2.0

[Ahmed Eldawy]

Hi,
 I've been using Hadoop 1.x for a few months and it was working fine. Now,
I want to migrate to hadoop-2.x but I'm having troubles starting it. In
Hadoop 1.x, I used to configure core-site.xml and mapred-site.xml to be
able to start master and slave on one machine.
In hadoop-2.2.0, I followed the instructions on
http://hadoop.apache.org/docs/r2.2.0/hadoop-project-dist/hadoop-common/SingleCluster.html
Whenever I start yarn or HDFS I find this error in the logs
java.lang.NoSuchMethodError:

Also there is a warning that seems to be related.
SLF4J: The requested version 1.6.99 by your slf4j binding is not compatible
with [1.5.5, 1.5.6]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further
details.

Any suggestions of how to fix it?
