Hadoop-2.6.0 Namenode not getting formatted

Question

I have just install Hadoop 2.6.0, While formatting name node, it halts at following lines and no exit code returns.

STARTUP_MSG: build = https://git-wip-us.apache.org/repos/asf/hadoop.git -r e3496499ecb8d220fba99dc5ed4c99c8f9e33bb1; compiled by 'jenkins' on 2014-11-13T21:10Z STARTUP_MSG: java = 1.7.0_79

Seems you used a wrong command.The commands related to hdfs are available in this url

Use any of the following command command

hadoop namenode -format

OR

hdfs namenode -format
