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