never seen 50075 before, but 50070 is the local NameNode, I suggest you format the NameNode to have a try:

rm -r /tmp/hadoop-*;
bin/hadoop namenode -format;
./bin/start-all.sh

After cleaning up the /tmp/hadoop* directory my name node is working fine. – Yuvaraj Loganathan Jun 15 '15 at 12:09

Check your port configurations. Here is a list of hadoop daemon configurable parameters

dfs.http.address: The address and the base port where the dfs namenode web ui will listen on. If the port is 0 then the server will start on a free port.

The default for the name node is usually set to port 50070, so try localhost:50070.

http://hadoop.apache.org/common/docs/r0.20.2/hdfs-default.html

I think you mean core-site.xml (not code-site.xml). The fs.default.name configuration here does not determine the location of the hadoop web ui/dashboard. This is the port used by data nodes to communicate with the name node.
