Unrecognized VM option 'MaxPermSize=512m' when running Zeppelin

When I try to run Zeppelin by either bin/zeppelin.sh or bin/zeppelin-deamon.sh start I was getting the following error message. Unrecognized VM option 'MaxPermSize=512m' Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
