Replace 127.0.1.1 with 127.0.0.1 in /etc/hosts..Also add the
hadoop-core*.jar from your HADOOP_HOME and common-cofigurations from
the HADOOP_HOME/lib to your HBASE_HOME/lib folder.

Mohammad Tariq

Shaharyar,
Did you format the namenode ("hadoop namenode -format")?
What do the namenode logs say?
- Dae

Please post your log files under /var/log directory. You are moreeither
missing something in the hdfs conf file or it is a problem with your hosts
file and name resolution for the namenode.
