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- -Dhadoop.auth.version=2.7. -Ddistcp.version=2.7. -Dhadoop.version=2.7. -Dsqoop.version=1.4. -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./share/lib/sqoop/

cp mysql-connector-java-5.1.-bin.jar /usr/local/oozie-4.3./share/lib/sqoop/

hdfs dfs -copyFromLocal /usr/local/oozie-4.3./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. 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.-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

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>

        <name>oozie.service.ProxyUserService.proxyuser.hadoop.hosts</name>

        <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>

    <property>

        <name>oozie.service.ProxyUserService.proxyuser.hadoop.groups</name>

        <value>*</value>

        <description>

            List of groups the '#USER#' user is allowed to impersonate users

            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>

    </property>

    <!-- 20180110 add -->

    <property>

        <name>oozie.service.JPAService.create.db.schema</name>

          <value>false</value>

        </property>

    <property>

        <name>oozie.service.JPAService.jdbc.driver</name>

    </property>

    <property>

        <value>oozie</value>

    </property>

    <property>

        <name>oozie.service.JPAService.jdbc.password</name>

        <value>password</value>

        <description>

                DB user password.

                IMPORTANT: if password is emtpy leave a 1 space string, the service trims the value,

                if empty Configuration assumes it is NULL.

        </description>

    </property>

    <property>

        <name>oozie.service.HadoopAccessorService.hadoop.configurations</name>

        <value>*=/usr/local/hadoop/etc/hadoop</value>

    <property>

         <name>oozie.service.SparkConfigurationService.spark.configurations</name>

         <value>/user/oozie/share/lib</value>

    </property>

    <property>

        <name>oozie.use.system.libpath</name>

        <value>true</value>

        <description>

                Default value of oozie.use.system.libpath. If user haven't specified =oozie.use.system.libpath=

                in the job.properties and this value is true and Oozie will include sharelib jars for workflow.

        </description>

    </property>

    <property>

        <name>oozie.subworkflow.classpath.inheritance</name>

        <value>true</value>

    </property>

</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：

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

5. 常用oozie的命令
