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

oozie4.3.0的安装与配置+hadoop2.7.3

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,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

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。




    

    

    
        oozie.service.ProxyUserService.proxyuser.hadoop.hosts
        *
        
            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.
        
    
        oozie.service.ProxyUserService.proxyuser.hadoop.groups
        *
        
            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.
        
    
        oozie.service.JPAService.create.db.schema
          false
        
        oozie.service.JPAService.jdbc.driver
        com.mysql.jdbc.Driver
    
        oozie.service.JPAService.jdbc.url
        jdbc:mysql://dwtest-name1:33061/ooziecreateDatabaseIfNotExist=true
    
        oozie.service.JPAService.jdbc.username
        oozie
    
        oozie.service.JPAService.jdbc.password
        password
        
                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.
        
    
        oozie.service.HadoopAccessorService.hadoop.configurations
        *=/usr/local/hadoop/etc/hadoop
    
        oozie.service.HadoopAccessorService.action.configurations
        *=/usr/local/hadoop/etc/hadoop
    
         oozie.service.SparkConfigurationService.spark.configurations
         *=/usr/local/spark/conf
    
         oozie.service.WorkflowAppService.system.libpath
         /user/oozie/share/lib
    
        oozie.use.system.libpath
        true
        
                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.
        
    
        oozie.subworkflow.classpath.inheritance
        true
    

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

oozie4.3.0的安装与配置+hadoop2.7.3

可以在mysql的oozie数据库中看到以下表被创建:

oozie4.3.0的安装与配置+hadoop2.7.3

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

oozie4.3.0的安装与配置+hadoop2.7.3

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:

oozie4.3.0的安装与配置+hadoop2.7.3

oozie4.3.0的安装与配置+hadoop2.7.3

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

desc

command

查看共享库pig包

oozie admin -oozie http://localhost:11000/oozie -shareliblist spark

查看共享库

oozie admin -oozie http://localhost:11000/oozie -shareliblist

提交任务

oozie job -oozie http://localhost:11000/oozie -config job.properties -submit

执行任务

oozie job -oozie http://localhost:11000/oozie -config job.properties -run

杀死任务

oozie job -oozie http://localhost:11000/oozie -kill jobid

重新运行任务

oozie job -oozie http://localhost:11000/oozie -config job.properties -rerun jobid

改变作业参数

oozie job -oozie http://localhost:11000/oozie -change jobid -value concurrency=1000;endtime=2018-01-10

检查作业状态

oozie job -oozie http://localhost:11000/oozie -info jobid

查看作业日志

oozie job -oozie http://localhost:11000/oozie -log jobid

检查XML是否符合规范

oozie calidate myapp/workflow.xml

help查询:

oozie help calidata //查询所有命令
oozie help admin
oozie help job
