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.
