Description

When start-dfs.sh is run by root user, we got the following error message:

1. start-dfs.sh
   Starting namenodes on [localhost ]
   localhost: namenode running as process 2556. Stop it first.
   localhost: starting datanode, logging to /usr/hadoop/hadoop-common-0.23.0-SNAPSHOT/bin/../logs/hadoop-root-datanode-cspf01.out
   localhost: Unrecognized option: -jvm
   localhost: Could not create the Java virtual machine.

The -jvm options should be passed to jsvc when we starting a secure
datanode, but it still passed to java when start-dfs.sh is run by root
while secure datanode is disabled. This is a bug of bin/hdfs.
