Please ensure hbase-*.jar, Guava-r*.jar, protobuf-*.jar & zookeeper.jar in your classpath.
>export > HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/usr/local/hbase-0.92.1-security/lib/ This will not add all the jars into the classpath. You have to iterate the lib folder and then you have to add to HADOOP_CLASSPATH. You can copy all the above jars into the hadoop lib directly, if ur not able to do this.

Sorry about that.

But I have explicitly set it already. Am I missing anything still?
