Hadoop on OSX 10.7

When starting Hadoop using I kept seeing the following in my log file
"Unable to load realm info from SCDynamicStore"
A workaround is suggested on the Hadoop Jira under HADOOP-7489 which is to specify kerberos config on the command line:
This works perfectly but is easier if you add it into the HADOOP_OPTS environment variable in $HADOOP_HOME/conf/ Mine looks like this:
export HADOOP_OPTS="-server"
