I am stuck and can't login... When I get into the ubuntu login screen and enter my password, it takes me back to the same screen. I was able to install ubuntu and run it for a few days. I was trying to install Apache hive but received some errors. The issue started when I modified my /etc/profile.d folder by placing a hadoop.sh file in it based on the inputs below http://stackoverflow.com/questions/17688466/cannot-find-hadoop-installation-hadoop-home-must-be-set-or-hadoop-must-be-in-t
After I restarted my m/c, I have not been able to login. I am now unable to remove the hadoop.sh file from root and tty1 as it says 'read only filesystem'. Please help.
