Can anyone say reasons for not showing hadoop demons in jps?

326 views Asked by At

I am using hadoop 2.7.3 version and after configuration namenode is not showing in jps. can anyone say what is the reason i gave correct permissions to the concerned files. I have deleted /tmp files and recreated and after reformatting the namenode same problem i am facing. Thanks in advance.
