问题
I installed Hadoop and Pig using brew install hadoop and brew install pig.
I read here that you will to get Unable to load realm info from SCDynamicStore error message unless you add:
export HADOOP_OPTS="-Djava.security.krb5.realm=OX.AC.UK -Djava.security.krb5.kdc=kdc0.ox.ac.uk:kdc1.ox.ac.uk"
to your hadoop-env.sh file, which I have.
However, when I run hadoop namenode -format, I still see:
java[1548:1703] Unable to load realm info from SCDynamicStore
amongst the outputs.
Anyone know why I'm still getting it?

As dturnanski suggests, you need to use an older JDK. You can set this in the hadoop-env.sh file by changing the JAVA_HOME setting to:
export JAVA_HOME=`/usr/libexec/java_home -v 1.6`
(Note the grave quotes here.) This fixed the problem for me.
