= Hadoop、Hbase、Zookeeper安裝 =

== 前言 ==
由於Nutch2.0開始，已經可以將索引結果存入Hbase，但由於Hbase內建的Zookeeper似乎沒有太穩定，因此自己手動整合才是王道...

== 安裝環境 ==
 * OS: Ubuntu12.04
 * Java: OpenJDK 6

== 套件版本 ==
 * Hadoop 1.0.3
 * Hbase 0.90.6(沒有選用最新的原因是因為Nutch官網上有提到0.90.x為他們的測試環境)
 * Zookeper 3.3.6

== 安裝Hadoop ==
=== 下載＆解壓縮Hadoop1.0.3 ===

=== 修改$HAHOOP_HOME/conf/hadoop-env.sh ===
 * 設定JAVA_HOME
{{{
#!text
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk
}}}
=== 修改$HAHOOP_HOME/conf/core-site.xml ===
{{{
#!text
<configuration>
     <property>
         <name>fs.default.name</name>
         <value>hdfs://localhost:9000</value>
     </property>
</configuration>
}}}
=== 修改$HAHOOP_HOME/conf/mapred-site.xml ===
{{{
#!text
<configuration>
 <property>
         <name>mapred.job.tracker</name>
         <value>localhost:9001</value>
     </property>
</configuration>
}}}
=== 修改$HAHOOP_HOME/conf/hdfs-site.xml ===
{{{
#!text
<configuration>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
  <property>
    <name>dfs.support.append</name>
    <value>true</value>
  </property>
</configuration>

}}}
=== 格式化HDFS ===
{{{
shunfa@shunfa-vmmVBox:/opt/hadoop-1.0.3$ bin/hadoop namenode -format
}}}
=== 啟動Hadoop ===
{{{
shunfa@shunfa-vmmVBox:/opt/hadoop-1.0.3$ bin/start-all.sh
}}}
== 安裝Zookeeper ==
=== 下載並解壓縮zookeeper到/opt/ ===

=== 建立zookeeper運作時需要的目錄並複製預設設定檔 ===
{{{
~$ cd /opt/zookeeper-3.3.6/
~$ sudo mkdir /var/zookeeper
~$ sudo chown -R shunfa:shunfa /var/zookeeper
~$ sudo chown -R shunfa:shunfa /opt/zookeeper-3.3.6/
~$ cp conf/zoo_sample.cfg conf/zoo.cfg
}}}
=== 修改zoo.cfg ===
{{{
#!text
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
}}}

=== 啟動 ===
{{{
~$ /opt/zookeeper-3.3.6/bin/zkServer.sh start
}}}

== 安裝Hbase ==
=== 下載並解壓縮Hbase到/opt/ ===
=== 修改 /opt/hbase-0.90.6/conf/hbase-env.sh ===
{{{
#!text
export HBASE_MANAGES_ZK=false
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk
export HBASE_HEAPSIZE=256
export HBASE_CLASSPATH=/opt/hadoop-1.0.3/conf
}}}
=== 修改 /opt/hbase-0.90.6/conf/hbase-site.xml ===
{{{
#!text
<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:54310/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/var/zookeeper</value>
  </property>
  <property>
    <name>dfs.support.append</name>
    <value>true</value>
  </property>
 <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
 <property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2181</value>
  </property>
</configuration>
}}}
=== 複製相關lib ===
{{{
~$ cp $HADOOP_HOME/lib/commons-configuration-1.6.jar $HBASE_HOME/lib/
~$ cp $HADOOP_HOME/hadoop-core-1.0.3.jar $HBASE_HOME/lib/
}}}

=== 啟動 ===
{{{
~$ /opt/hbase-0.90.6/bin/start-hbase.sh
}}}

== 完成 ==
 * 執行結果如下：
