我正在centos 6.5 64位rpm上手动安装hortonworks数据平台2.2。在格式化namenode insufficent parameters期间，会“抛出”错误
这些是手册中的说明：

Format and Start HDFS
1. Execute these commands at the NameNode host machine:
su - hdfs
/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh
namenode -format
/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh -
-config $HADOOP_CONF_DIR start namenode

但在格式化命令期间：

[root@virtual ~]# su - hdfs
[hdfs@virtual ~]$ /usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh namenode -format
Usage: hadoop-daemon.sh [--config <conf-dir>] [--hosts hostlistfile] [--script script] (start|stop) <hadoop-command> <args...>

不通过参数检查：

# Runs a Hadoop command as a daemon.

# 

# Environment Variables

# 

# HADOOP_CONF_DIR  Alternate conf dir. Default is ${HADOOP_PREFIX}/conf.

# HADOOP_LOG_DIR   Where log files are stored.  PWD by default.

# HADOOP_MASTER    host:path where hadoop code should be rsync'd from

# HADOOP_PID_DIR   The pid files are stored. /tmp by default.

# HADOOP_IDENT_STRING   A string representing this instance of hadoop. $USER by default

# HADOOP_NICENESS The scheduling priority for daemons. Defaults to 0.

## 

export HADOOP_HOME=/usr/hdp/2.2.0.0-2041/hadoop
usage="Usage: hadoop-daemon.sh [--config <conf-dir>] [--hosts hostlistfile] [--script script] (start|stop) <hadoop-command> <args...>"

# if no args specified, show usage

if [ $# -le 1 ]; then
  echo $usage
  exit 1
fi

我不确定这是脚本中的错误还是手册中的错误。。。
任何暗示都会有帮助
谢谢
