Subject [jira] [Created] (HDFS-1943) fail to start datanode while start-dfs.sh is executed by root user

fail to start datanode while start-dfs.sh is executed by root user
------------------------------------------------------------------

                 Key: HDFS-1943
                 URL: https://issues.apache.org/jira/browse/HDFS-1943
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.23.0
            Reporter: Wei Yongjun
            Priority: Blocker
             Fix For: 0.23.0


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.
