oozie 运行demo

昨晚装好了oozie，能启动了，并且配置了mysql作为数据库，好了，今天要执行oozie自带的demo了，好家伙，一执行就报错！报错很多，就不一一列举了，就说我最后解决的方法吧。

oozie job -oozie http://localhost:11000/oozie -config examples/apps/map-reduce/job.properties –run

这句话需要在oozie的目录里面执行，然后在网上查了很多资料，最后搞定了，需要修改三个配置文件。

在说修改配置文件之前，还漏了一些东西，先补上，首先我们需要解压目录下面的oozie-examples.tar.gz，oozie-client-3.3.2.tar.gz，

oozie-sharelib-3.3.2.tar.gz，然后把examples和share目录上传到fs上面去。

hadoop fs -put examples examples

hadoop fs -put share share

然后在/etc/profile配置oozie-client的环境变量。

接下来说怎么解决的oozie的吧。

1.修改oozie的conf目录下的oozie-site.xml

增加以下内容：

<property>
       <name>oozie.services</name>
        <value>
            org.apache.oozie.service.SchedulerService,
            org.apache.oozie.service.InstrumentationService,
            org.apache.oozie.service.CallableQueueService,
            org.apache.oozie.service.UUIDService,
            org.apache.oozie.service.ELService,
            org.apache.oozie.service.AuthorizationService,
            org.apache.oozie.service.MemoryLocksService,
            org.apache.oozie.service.DagXLogInfoService,
            org.apache.oozie.service.SchemaService,
            org.apache.oozie.service.LiteWorkflowAppService,
            org.apache.oozie.service.JPAService,
            org.apache.oozie.service.StoreService,
            org.apache.oozie.service.CoordinatorStoreService,
            org.apache.oozie.service.SLAStoreService,
            org.apache.oozie.service.DBLiteWorkflowStoreService,
            org.apache.oozie.service.CallbackService,
            org.apache.oozie.service.ActionService,
            org.apache.oozie.service.ActionCheckerService,
            org.apache.oozie.service.RecoveryService,
            org.apache.oozie.service.PurgeService,
            org.apache.oozie.service.CoordinatorEngineService,
            org.apache.oozie.service.BundleEngineService,
            org.apache.oozie.service.DagEngineService,
            org.apache.oozie.service.CoordMaterializeTriggerService,
            org.apache.oozie.service.StatusTransitService,
            org.apache.oozie.service.PauseTransitService,
        org.apache.oozie.service.HadoopAccessorService
        </value>
        <description>
            All services to be created and managed by Oozie Services singleton.
            Class names must be separated by commas.
        </description>
    </property>

<property>
       <name>oozie.service.ProxyUserService.proxyuser.cenyuhai.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.cenyuhai.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> 

2.修改oozie-env.sh，增加以下内容

export OOZIE_CONF=${OOZIE_HOME}/conf
export OOZIE_DATA=${OOZIE_HOME}/data
export OOZIE_LOG=${OOZIE_HOME}/logs
export CATALINA_BASE=${OOZIE_HOME}/oozie-server
export CATALINA_TMPDIR=${OOZIE_HOME}/oozie-server/temp
export CATALINA_OUT=${OOZIE_LOG}/catalina.out

3.修改所有节点的hadoop的配置文件core-site.xml,

<property>
    <name>hadoop.proxyuser.cenyuhai.hosts</name>
    <value>hadoop.Master</value>
 </property>
 <property>
    <name>hadoop.proxyuser.cenyuhai.groups</name>
    <value>cenyuhai</value>
</property>

然后重启就可以执行了，里面的cenyuhai是我的本机账号。

补充：在进行完上述配置之后，作业可以提交了，但是提交了MR作业之后，在web页面中查看，遇到了一个错误：

JA006: Call to localhost/127.0.0.1:9001 failed on connection exception: java.net.ConnectException: Connection refused

这个问题排查了很久，都没有得到解决 ，最后通过修改job.properties，把jobTracker从localhost：9001改成下面的全称才行，这个可能跟我的hadoop的

jobTracker设置有关，所以遇到有这方面问题的童鞋可以试试。

nameNode=hdfs://192.168.1.133:9000
jobTracker=http://192.168.1.133:9001

接下来我们接着运行hive的demo，运行之前记得修改hive的demo的job.properties，改为上面写的那样。

然后提交，提交成功了，但是在web页面上查看状态为KILLED，被干掉了。。。

错误代码：JA018，错误消息：org/apache/hadoop/hive/cli/CliDriver

然后我就想着可能是jar包的问题，删掉share目录下的hive目录里的所有jar包，然后把自己机器上的hive的所有jar包复制到该目录下。

然后上传到共享目录上：

hadoop fs -put share share

再次提交，就可以查看到成功的状态啦！

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

但是这个坑爹的玩意儿，其实是把数据插入到了Derby中。。。无语了，虽然现实成功了，但是没有用。。。因为我们配置了外置的mysql数据库，那怎么办呢？

需要修改workflow.xml，把其中的configuration的配置节改成下面的样子。

<configuration>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
        <property>
                <name>hive.metastore.local</name>
                <value>true</value>
            </property>
            <property>
                <name>javax.jdo.option.ConnectionURL</name>
                <value>jdbc:mysql://192.168.1.133:3306/hive?createDatabaseIfNotExist=true</value>
            </property>
            <property>
                    <name>javax.jdo.option.ConnectionDriverName</name>
                <value>com.mysql.jdbc.Driver</value>
            </property>
            <property>
                <name>javax.jdo.option.ConnectionUserName</name>
                    <value>hive</value>
            </property>
            <property>
                <name>javax.jdo.option.ConnectionPassword</name>
                <value>mysql</value>
               </property>
        <property>
              <name>hive.metastore.warehouse.dir</name>
              <value>/user/hive/warehouse</value>
        </property>
 </configuration>

然后提交之后，在hive中就可以查询到你所建立的表啦，oh，yeah！
