hadoop的單機版安裝和HBase的搭建

1. 安裝jdk1.7的環境   下載hadoop. hadoop-2.5.2.tar.gz版本

2.進入hadoop的網站，點擊左下角的Documentation,找到對應的版本 ，點擊進入，找到Single Node Setup 的說明文檔，按照文檔說明開始配置

1. 編輯etc/hadoop/hadoop-env.sh 

2. # set to the root of your Java installation
     export JAVA_HOME=/usr/java/latest (java的環境位置)

3. Use the following:

   etc/hadoop/core-site.xml:

   <configuration>
       <property>
           <name>fs.defaultFS</name>
           <value>hdfs://localhost:8020</value> (ip地址)
       </property>
   </configuration>

   etc/hadoop/hdfs-site.xml:

   <configuration>
       <property>
           <name>dfs.replication</name>
           <value>1</value>
       </property>
   </configuration>

配置YARN on Single Node

Configure parameters as follows:

etc/hadoop/mapred-site.xml:

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
</configuration>

etc/hadoop/yarn-site.xml:

<configuration>
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
</configuration>

 配置 hadoop.tmp.dir

在hadoop文件中建立data目錄

在etc/hadoop/core-site.xml:中添加  

<property>
        <name>hadoop.tmp.dir</name>
        <value>/bigdata/softwares/hadoop-2.5.2/data/tmp</value>
    </property>

執行操做

1. Format the filesystem: 格式化信息 

   $ bin/hdfs namenode -format

2. Start NameNode daemon and DataNode daemon:

   $ sbin/start-dfs.sh

3. $ sbin/start-yarn.sh

4. The hadoop daemon log output is written to the $HADOOP_LOG_DIR directory (defaults to $HADOOP_HOME/logs).

5. Browse the web interface for the NameNode; by default it is available at:
   • NameNode - http://localhost:50070/

 hbase

 Example hbase-site.xml for Standalone HBase

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://ip:8080/data</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/bigdata/softwares/hbase-1.2.3/data/zkData</value>
  </property>
</configuration>

<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>

修改 regionserver 中的ip地址

bin/hbase-daemon.sh start zookeeper

 bin/hbase-daemon.sh start master

 bin/hbase-daemon.sh start regionserver

http://192.168.1.23:16030/rs-status 端口邊了
