【原】centos6.5下cdh4.6 Oozie安装

0、oozie只需安装在一台服务器上，这里选择在namenode上来安装；安装用户为cloud-user

1、安装Oozie包：

   sudo yum install -y oozie oozie-client

2、对于yarn来说，需要修改/etc/oozie/conf/oozie-env.sh中：

   CATALINA_BASE=/usr/lib/oozie/oozie-server

3、配置mysql：

   yum install -y mysql-server

   创建数据库：

   mysql -u root -p

   mysql> create database oozie;

   mysql> grant all privileges on oozie.* to 'oozie'@'localhost' identified by 'oozie';

   mysql> grant all privileges on oozie.* to 'oozie'@'%' identified by 'oozie';

   mysql> exit

4、配置oozie-site.xml:

 <property>
      <name>oozie.service.JPAService.jdbc.driver</name>
      <value>com.mysql.jdbc.Driver</value>
 </property>
 <property>
      <name>oozie.service.JPAService.jdbc.url</name>
      <value>jdbc:mysql://10.0.0.2:3306/oozie</value>
 </property>
 <property>
      <name>oozie.service.JPAService.jdbc.username</name>
      <value>oozie</value>
 </property>
 <property>
      <name>oozie.service.JPAService.jdbc.password</name>
      <value>oozie</value>
 </property>
 <property>
      <name>oozie.action.mapreduce.uber.jar.enable</name>
      <value>true</value>
 </property>
 <property>
      <name>oozie.service.HadoopAccessorService.supported.filesystems</name>
      <value>hdfs,viewfs</value>
 </property>
   <property>
      <name>oozie.service.ProxyUserService.proxyuser.cloud-user.hosts</name>
      <value>*</value>
 </property>
  <property>
      <name>oozie.service.ProxyUserService.proxyuser.cloud-user.groups</name>
      <value>*</value>
 </property>

5、拷贝JDBC Driver：

    sudo cp /usr/share/java/mysql-connector-java.jar /var/lib/oozie

    sudo cp /usr/lib/hadoop/lib/hadoop-lzo-cdh4-0.4.15-gplextras.jar /var/lib/oozie

    sudo cp /usr/lib/hadoop/lib/hadoop-lzo.jar /var/lib/oozie

6、创建oozie 数据库scheme,这一步骤需要root来执行：

    su -

　　/usr/lib/oozie/bin/ooziedb.sh create -sqlfile oozie-create.sql

    /usr/lib/oozie/bin/ooziedb.sh create -run  

7、使能web console：

    wget http://archive.cloudera.com/gplextras/misc/ext-2.2.zip

　　sudo mv ext-2.2.zip /var/lib/oozie/

    cd /var/lib/oozie/ && sudo unzip ext-2.2.zip

　　sudo chown -R oozie:oozie /var/lib/oozie/

8、安装Oozie ShareLib：

    sudo -u hdfs hadoop fs -mkdir /user/oozie

    sudo -u hdfs hadoop fs -chown oozie:oozie /user/oozie

    mkdir /tmp/ooziesharelib

    cd /tmp/ooziesharelib

    tar xzf /usr/lib/oozie/oozie-sharelib-yarn.tar.gz

    sudo -u oozie hadoop fs -put share /user/oozie/share

9、启动服务：

    sudo service oozie start

10、测试map-reduce：

　　添加/etc/hadoop/conf/core-site.xml

 <property>
    <name>hadoop.proxyuser.oozie.hosts</name>
    <value>10.0.0.2</value>
 </property>
 <property>
    <name>hadoop.proxyuser.oozie.groups</name>
    <value>*</value>
 </property> 

　　cp /usr/share/doc/oozie-3.3.2+100/oozie-examples.tar.gz .　　

　　tar -zxvf oozie-examples.tar.gz

　　修改example/apps/map-reduce/job.properties 

　　nameNode=hdfs://10.0.0.2:8020
　　jobTracker=10.0.0.2:8032 端口改为/etc/hadoop/conf/yarn-site.xml中 'yarn.resourcemanager.address ' 项的值

hadoop fs -put examples

　　oozie job -oozie http://10.0.0.3:11000/oozie -config  ./examples/apps/no-op/job.properties -run

　　Job ID : 0000000-140508214215146-oozie-oozi-W

　　通过oozie job -oozie http://10.0.0.3:11000/oozie -log 0000000-140508214215146-oozie-oozi-W查看log

　　通过oozie job -oozie http://10.0.0.3:11000/oozie -info 0000000-140508214215146-oozie-oozi-W查看信息

　　通过http://namenode:11000/oozie查看web console
