I keep getting this weird error message when Hadoop starts up on OSX 10.7. Here's the error message:
Unable to load realm info from SCDynamicStore put: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory /user/travis/input/conf. Name node is in safe mode.
Has anyone seen this before? If so, what should I do? Thank you.

Hi ITKE, 
Just add to your hadoop-env.sh file:
export HADOOP_OPTS=”-Djava.security.krb5.realm=OX.AC.UK -Djava.security.krb5.kdc=kdc0.ox.ac.uk:kdc1.ox.ac.uk”
I hope it will assist you in resolving  your issues.
Thanks & Regards
