oozie4.3.0的安装与配置 + hadoop2.7.3

安装步骤

• mysql的配置
• oozie的安装
• oozie的配置
• oozie的启动与登录
• 常用oozie的命令

1. mysql的配置

mysql的安装自行解决，然后在mysql上

创建oozie数据库，创建oozie用户名和密码，并赋值oozie账号登陆oozie数据库的权限。

mysql -u root -proot
create database oozie;  
//(设置oozie数据库的访问权限)  
grant all privileges on oozie.* to 'oozie'@'%' identified by 'password';             
FLUSH PRIVILEGES;  

注意要删除msyql中两个空的用户，否则会一直报用户无权限。

 

2. oozie的安装

2.1 oozie的下载与编译

https://mirrors.tuna.tsinghua.edu.cn/apache/oozie/4.3.0/oozie-4.3.0.tar.gz

官方提供的oozie只是源码，需要自己编译，解压缩，使用以下命令编译：

./mkdistro.sh -Phadoop-2 -Dhadoop.auth.version=2.7.3 -Ddistcp.version=2.7.3 -Dhadoop.version=2.7.3 -Dsqoop.version=1.4.6 -DskipTests 

编译过程中会有3处错误(点这里参考这篇文章)，都是镜像库中包找不到，所以需要自己下载，然后放到本地maven仓库目录下即可。

编译成功后，打包的文件路径为：oozie-4.3.0/distro/target/oozie-4.3.0-distro.tar.gz

2.2 oozie的安装

1）  解压缩包oozie-4.3.0-distro.tar.gz到/usr/local/目录下，然后进入目录oozie-4.3.0,分别解压缩里面的三个压缩包oozie-client-4.3.0.tar.gz、oozie-examples.tar.gz、oozie-sharelib-4.3.0.tar.gz

完成后的文件列表如下：

2） 在hdfs上创建/user/oozie目录，然后将share目录上传到hdfs中的/user/oozie目录。

将mysql驱动和oracle驱动放到share/lib目录下, 后面使用sqoop的时候，会使用hdfs的/user/oozie/share/lib/sqoop/目录下的jar包。

cp ojdbc*.jar /usr/local/oozie-4.3.0/share/lib/sqoop/
cp mysql-connector-java-5.1.35-bin.jar /usr/local/oozie-4.3.0/share/lib/sqoop/
hdfs dfs -copyFromLocal /usr/local/oozie-4.3.0/share/ /user/oozie

3）  在/usr/local/oozie目录下创建libext文件夹，然后复制hadoop的lib目录下的文件到/usr/local/oozie/libext下。

ln -s oozie-4.3.0 oozie
cd oozie
mkdir libext
cp ${HADOOP_HOME}/share/hadoop/*/*.jar libext/
cp ${HADOOP_HOME}/share/hadoop/*/lib/*.jar libext/

添加ext-2.2.zip和mysql驱动包、oracle驱动包到libext

cp ext-2.2.zip /usr/local/oozie/libext/
cp mysql-connector-java-5.1.35-bin.jar /usr/local/oozie/libext/

4）  修改oozie-4.3.0/oozie-server/conf/server.xml文件，注释掉下面的记录

<!--<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />-->

5）  打war包

在bin目录下执行命令：

./oozie-setup.sh prepare-war

war文件最终保存在/usr/local/oozie/oozie-server/webapps目录下

 

 

3. oozie的配置

3.1 设置环境变量/etc/profile

#180112 oozie path
export OOZIE_HOME=/usr/local/oozie
export PATH=$OOZIE_HOME/bin:$PATH
export OOZIE_CONFIG=/usr/local/oozie/conf

# 这里要注意地址后面要带/oozie，否则报404错误, 踩过的坑只有自己知道痛苦

export OOZIE_URL=http://dwtest-name1:11000/oozie

  3.2 修改配置文件/usr/local/oozie/conf/oozie-site.xml

默认conf文件夹下的oozie-site.xml文件都是注释的，需要自己添加以下内容。

<?xml version="1.0"?>
<configuration>

    <!--
        Refer to the oozie-default.xml file for the complete list of
        Oozie configuration properties and their default values.
    -->

    <!-- Proxyuser Configuration -->

    <property>

        <value>*</value>
        <description>
            List of hosts the '#USER#' user is allowed to perform 'doAs'
            operations.

            The '#USER#' must be replaced with the username o the user who is
            allowed to perform 'doAs' operations.

            The value can be the '*' wildcard or a list of hostnames.

            For multiple users copy this property and replace the user name
            in the property name.
        </description>
    </property>

            from to perform 'doAs' operations.

            The '#USER#' must be replaced with the username o the user who is
            allowed to perform 'doAs' operations.

            The value can be the '*' wildcard or a list of groups.

            For multiple users copy this property and replace the user name
            in the property name.

        <description>

                IMPORTANT: if password is emtpy leave a 1 space string, the service trims the value,
                if empty Configuration assumes it is NULL.
        </description>
    </property>

        </description>
    </property>

    <property>
        <name>oozie.subworkflow.classpath.inheritance</name>
        <value>true</value>

</configuration>

 

 3.3 创建元数据表

在/usr/local/oozie/bin目录下执行以下命令生成sql文件，并创建元数据表

bin/ooziedb.sh create -sqlfile oozie.sql -run

 

可以在mysql的oozie数据库中看到以下表被创建：

3.4 修改core-site.xml文件(视具体环境设置)

 如果调用oozie job的账号与hadoop不一致，则需要修改hadoop的配置文件core-site.xml，添加调用oozie job的用户组，由于我使用的都是hadoop账户，则不需要做任何修改。

修改完后，拷贝到Second name节点。使用以下命令来刷新，不需要重启hadoop集群。

scp core-site.xml hadoop@dwtest-name2:/usr/local/hadoop/etc/hadoop/
hdfs dfsadmin -refreshSuperUserGroupsConfiguration  
yarn rmadmin -refreshSuperUserGroupsConfiguration

  

4. oozie的启动与登录

启动与停止的脚本

bin/oozied.sh start
bin/oozied.sh stop

 启动时，显示如下：

 

登录: http://dwtest-name1:11000/oozie/

不兼容包的删除：

 oozie启动后会自动将war包解压生成一个oozie文件夹。

此时需要将/usr/local/oozie/oozie-server/webapps/oozie/WEB-INF/lib中包含hadoop2.6.0版本的包删除或者移走，

否则启动job会提示错误Error, java.lang.NoSuchFieldError: HADOOP_CLASSPATH
