Hadoop single node cluster error on

I've followed each and every step for installing Hadoop from this website https://www.digitalocean.com/community/tutorials/how-to-install-hadoop-on-ubuntu-13-10

All the steps go fine except the last step where I start Hadoop using start-dfs.sh and lot of errors come. Please help. The errors are :

Your user account doesn't have the correct permissions to the /usr/local/hadoop directory, so Hadoop is failing when trying to create its logs. Try running sudo chown -R <username> /usr/local/hadoopwhere is your username. To get your username, you can use the whoami command.
