oozie安装

安装

1.缺包去：https://repo.spring.io/simple/hortonworks/org/apache/

$ bin/mkdistro.sh [-DskipTests]Running =mkdistro.sh= will create the binary distribution of Oozie. By default, oozie war will not contain hadoop andhcatalog libraries, however they are required for oozie to work. There are 2 options to add these libraries:1. At install time, copy the hadoop and hcatalog libraries to libext and run oozie-setup.sh to setup oozie war. This issuitable when same oozie package needs to be used in multiple set-ups with different hadoop/hcatalog versions.2. Build with -Puber which will bundle the required libraries in the oozie war. Further, the following options areavailable to customise the versions of the dependencies:-P<profile> - default hadoop-1. Valid are hadoop-1, hadoop-0.23, hadoop-2 or hadoop-3. Choose the correct hadoopprofile depending on the hadoop version used.-Dhadoop.version=<version> - default 1.2.1 for hadoop-1, 0.23.5 for hadoop-0.23, 2.3.0 for hadoop-2 and 3.0.0-SNAPSHOT    for hadoop-3-Dhadoop.auth.version=<version> - defaults to hadoop version-Ddistcp.version=<version> - defaults to hadoop version-Dpig.version=<version> - default 0.12.1-Dpig.classifier=<classifier> - default none-Dsqoop.version=<version> - default 1.4.3-Dsqoop.classifier=<classifier> - default hadoop100-Dtomcat.version=<version> - default 6.0.41-Dopenjpa.version=<version> - default 2.2.2-Dxerces.version=<version> - default 2.10.0-Dcurator.version=<version> - default 2.5.0-Dhive.version=<version> - default 0.13.1-Dhbase.version=<version> - default 0.94.2

cd  oozie-4.2.0/bin

./mkdistro.sh -DskipTests  -Puber -P hadoop-2                 -Puber会将第三方的包的打包进war包，比较方便。如果不加-Puber的话。编译好后的oozie.war包就没有依赖的jar文件。以后得自己下载依赖，放到libext目录下，然后自己打war包。

2.hbase-1.0.3.jar下载不到，在m2本地仓库中用hbase-0.9.XX.jar替换了，就是把名字改成1.0.3了----不知道会不会有后遗症

3. Failed to execute goal org.apache.maven.plugins:maven-site-plugin:2.0-beta-6:site (default) on project oozie-docs: The site descriptor cannot be resolved from the repository: Could not transfer artifact org.apache:apache:xml:site_en:16 from/to Codehaus repository (http://repository.codehaus.org/): repository.codehaus.org: unknown error

解决方式：

I was able to resolve it by editing the parent pom.xml file by removing the repository Codehaus repository

 <repository>
    <id>Codehaus repository</id>
    <url>http://repository.codehaus.org/</url>
    <snapshots>
      <enabled>false</enabled>
    </snapshots>
  </repository> 

或者替换链接

<repositories>
     <repository>
       <id>Codehaus repository</id>
       <name>codehaus-mule-repo</name>
       <url>https://repository-master.mulesoft.org/nexus/content/groups/public/
       </url>
       <layout>default</layout>
     </repository>
   </repositories>

编译后目标生产路径oozie-4.2.0/distro/target/oozie-4.2.0-distro.tar.gz

安装：

编译生成的oozie-4.2.0-distro.tar.gz 解压到相应目录这就是我们要的oozie 了。解压后得到oozie-4.2.0，cd到改目录下

1.下载ext-2.2.zip

　　　　解压oozie-4.0.1-distro.tar.gz包

　　　　mkdir libext

把hadoop的lib拷贝至libext目录下：cp /usr/local/hadoop/share/hadoop/*/*.jar libext/;cp /usr/local/hadoop/share/hadoop/*/lib/*.jar libext/

把hadoop与tomcat冲突jar包去掉--这个参考网络，不知道是不是必须

mv servlet-api-2.5.jar servlet-api-2.5.jar.bak

mv jsp-api-2.1.jar jsp-api-2.1.jar.bak

mv jasper-compiler-5.5.23.jar jasper-compiler-5.5.23.jar.bak

mv jasper-runtime-5.5.23.jar jasper-runtime-5.5.23.jar.bak 

2.bin/oozie-setup.sh prepare-war

3.上传共享lib 

tar -zxvf oozie-4.2.0/distro/target/oozie-4.2.0-distro/oozie-4.2.0/oozie-sharelib-4.2.0.tar.gz，会生成share目录，待会生成hdfs的sharelib目录的时候需要用到。

bin/oozie-setup.sh  sharelib  create -fs hdfs://node01:8020，红色部分改成自己hdfs url地址

 或者  hdfs dfs -put  /opt/oozie-4.2.0/share  /user/{username}

注意，与oozie-site.xml中的oozie.service.WorkflowAppService.system.libpath的值保持一致，所以必须放到/user/{username}这个目录下

4.代理设置

http://dongxicheng.org/mapreduce-nextgen/hadoop-secure-impersonation/

如果不设置，提交任务时会遇到类似的报错：

 hadoop is not allowed to impersonate hadoop

翻译过来意思是hadoop不允许模仿hadoop，也就是说hadoop没有代替hadoop提交任务的权限。

出现这个问题的原因在于OOZIE本身并不执行任何任务，也不会分发任务至Tasktracker。OOZIE和Hadoop集群唯一的交互是向Jobtracker提交任务，并通过回调URL或轮询的方式获取任务执行情况。

我们假定Hadoop集群安装在A账户下，OOZIE安装在某节点的B账户下，该账户属于C用户组。那么代理设置表示如下含义：A账户在该节点拥有代替C用户组提交任务的权限。 

在core-site.xml中添加

        <!-- OOZIE --> 

        <property> 

                <name>hadoop.proxyuser.hadoop.hosts</name> 

                <value>IP</value> 

        </property> 

        <property>

                <name>hadoop.proxyuser.hadoop.groups</name>

                <value>hadoop</value> 

        </property>

 

在配置项中，hadoop.proxyuser.hadoop.hosts和hadoop.proxyuser.hadoop.groups中的两个hadoop是我们上文提到的账户A，hadoop.proxyuser.hadoop.hosts对应的value需要填写OOZIE安装节点的IP，hadoop.proxyuser.hadoop.groups对应的value需要填写我们上文提到的用户组C。

由于一般Hadoop和OOZIE都安装在hadoop账户下，而hadoop账户又属于hadoop用户组。所以就出现了这种搞笑的配置，hadoop代替hadoop提交任务。 

不重启hadoop集群，而使配置生效

hdfs dfsadmin -refreshSuperUserGroupsConfiguration

  yarn rmadmin -refreshSuperUserGroupsConfiguration

注意用户名一定不能带点：如hadoop.proxyuser.xing.ming.groups

5.bin/oozie-setup.sh db create -run

可以在conf/oozie-site.xml中修改oozie 元数据db相关信息

6.bin/oozied.sh start

7.bin/oozie admin -oozie http://localhost:11000/oozie -status

可以直接访问http://localhost:11000/oozie
