Problem Starting Namenode 

Follow These TroubleShooting Tips:
 
1)Format NameNode 
  /bin/hadoop namenode -format
  NOTE:-Do not format a running Hadoop filesystem as you will lose all the data currently in the cluster (in HDFS)!
  
2)Port is not available for namenode to bind itself (check logs or use command -netstat to check ports )
  Port address are specified in core-site.xml, change the port address
