linux下安装hadoop以及myeclipse连接的配置

1.首先在linux上安装ssh服务，请查看我的安装ssh文章

2.接着安装hadoop

1>从网上下载hadooptar包  下载地址

2>用命令

tar -zxvf /下载路径/tar包

3>配置conf文件夹下的配置文件

hadoop-env.sh

增加jdk的安装路径

export JAVA_HOME=/usr/java/jdk-7

如果路径有空格，就用单引号把路径

core-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

	<property>
		<name>fs.default.name</name>
		<value>hdfs://xxx.xxx.xx.xxx:9000</value>
	</property>

     <property>  
          <name>hadoop.tmp.dir</name>
      <value>/tmp/hadoop/hadoop-${user.name}</value> 
     </property> 

 </configuration>

hdfs-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

	</property>
	<property>

</configuration>

mapred-site.xml

<!-- Put site-specific property overrides in this file. -->

<configuration>
    <property>
        <name>mapred.job.tracker</name>
        <value>xxx.xxx.xxx.xxx:9001</value>
    </property>

</configuration>

masters   slaves    把这个文件中的localhost改成电脑的ip

4>格式化namenode

进入到hadoop目录
bin/hadoop namenode -format

bin/hadoop start-all.sh


jps查看是否启动成功

13815 Jps
13762 TaskTracker
7409 SecondaryNameNode
7493 JobTracker
13236 NameNode
13454 DataNode

5>下载myeclipse连接hadoop的插件
