Linux Centos6 VM如何格式化namenode？

Question

I'm trying to start hadoop on my Centos6 VM linux. 我正在尝试在Centos6 VM Linux上启动hadoop。 these steps have been followed 遵循了这些步骤

yum install hadoop* mahout* oozie* hbase* hive* hue* pig* zookeeper* done yum install hadoop * mahout * oozie * hbase * hive * hue * pig * zookeeper *已完成
yum install java-1.7.0-openjdk-devel.x86_64 done 百胜安装java-1.7.0-openjdk-devel.x86_64完成
yum install sudo done 百胜安装须藤完成
yum install nano done 百胜安装纳米完成
sudo /etc/init.d/hadoop-hdfs-namenode init fail -->sudo: update-rc.d: command not found sudo /etc/init.d/hadoop-hdfs-namenode初始化失败-> sudo：update-rc.d：找不到命令

I checked etc/init.d and there is nothing like hadoop-hdfs-namenode. 我检查了etc / init.d，没有什么像hadoop-hdfs-namenode一样。 Instead of this command i found this hadoop namenode -format and executed. 我找到了这个hadoop namenode -format并执行了它，而不是这个命令。 And it worked then next step 然后工作就可以了

for i in hadoop-hdfs-namenode hadoop-hdfs-datanode ; 因为我在hadoop-hdfs-namenode hadoop-hdfs-datanode中； do sudo service $i start ; 做sudo服务$ i start; done 完成

I executed this command but got unrecognized service error. 我执行了此命令，但收到无法识别的服务错误。

When you first install Hadoop, you must configure it following this https://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-common/ClusterSetup.html 首次安装Hadoop时，必须按照以下https://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-common/ClusterSetup.html进行配置。

Use this command to format a new distributed filesystem and namenode 使用此命令格式化新的分布式文件系统和名称节点

$ $HADOOP_PREFIX/bin/hdfs namenode -format <cluster_name>
