Don't configure Hadoop to run as ROOT.
Instead use <hduser> or someother standard user.(created with useradd command)
I tried to configured with root and got following error and my datanode did not start. so finally
I created user with name:hduser and now I am up and running...
Best place to learn your first hadoop configuration is following page. Ignore Giraph configuration and take hadoop configuration part.
https://giraph.apache.org/quick_start.html
localhost: starting datanode, logging to /usr/local/hadoop/bin/../logs/hadoop-root-datanode-vm1.out
localhost: Unrecognized option: -jvm
localhost: Error: Could not create the Java Virtual Machine.
localhost: Error: A fatal exception has occurred. Program will exit.
