oozie框架案例之shellAction

oozie配置Shell脚本调度


MapReduce 
Hive
1、拷贝模版
$ cp -r examples/apps/shell/ oozie-apps

2、=========修改job.properties============

The corresponding job properties file used to submit Oozie job could be as follows:

oozie.wf.application.path=hdfs://localhost:8020/user/kamrul/workflows/script#Execute is expected to be in the Workflow directory.#Shell Script to runEXEC=script.sh#CPP executable. Executable should be binary compatible to the compute node OS.#EXEC=hello#Perl script#EXEC=script.pljobTracker=localhost:8021nameNode=hdfs://localhost:8020queueName=default

nameNode=hdfs://[hostname]:8020
jobTracker=[hostname]:8032
queueName=default
examplesRoot=oozie-apps


oozie.wf.application.path=${nameNode}/user/admin/${examplesRoot}/shell
EXEC=mem.sh

3、修改==============workflow.xml=============

How to run any shell script or perl script or CPP executable

<workflow-app xmlns='uri:oozie:workflow:0.3' name='shell-wf'>    <start to='shell1' />    <action name='shell1'>        <shell xmlns="uri:oozie:shell-action:0.1">            <job-tracker>${jobTracker}</job-tracker>            <name-node>${nameNode}</name-node>            <configuration>                <property>                  <name>mapred.job.queue.name</name>                  <value>${queueName}</value>                </property>            </configuration>            <exec>${EXEC}</exec>            <argument>A</argument>            <argument>B</argument>            <file>${EXEC}#${EXEC}</file> <!--Copy the executable to compute node's current working directory -->        </shell>        <ok to="end" />        <error to="fail" />    </action>    <kill name="fail">        <message>Script failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>    </kill>    <end name='end' /></workflow-app>

<start to="shell-node"/>
    <action name="shell-node">
        <shell xmlns="uri:oozie:shell-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <configuration>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
            </configuration>
            <exec>${EXEC}</exec>
            <file>${nameNode}/user/user01/${examplesRoot}/shell/${EXEC}#${EXEC}</file>
        </shell>
        <ok to="end"/>
        <error to="fail"/>
    </action>   
    <kill name="fail">
        <message>Shell action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>   
    <end name="end"/>


4、创建测试脚本
#!/bin/sh
/bin/date -R >> /opt/modules/cdh/oozie-4.0.0-cdh5.3.6/oozie-apps/shell/
1.log
/usr/bin/free -m >> /opt/modules/cdh/oozie-4.0.0-cdh5.3.6/oozie-apps/sh
ell/1.log
/bin/df -l >> /opt/modules/cdh/oozie-4.0.0-cdh5.3.6/oozie-apps/shell/1.
log
echo ------------------- >> /opt/modules/cdh/oozie-4.0.0-cdh5.3.6/oozie
-apps/shell/1.log


5.上传到HDFS对应目录
$ bin/hdfs dfs -put /opt/modules/oozie-4.0.0-cdh5.3.6/oozie-apps/shell /user/user01/oozie-apps/


6、执行：
$ bin/oozie job -oozie http://[hostname]:11000/oozie -config oozie-apps/shell/job.properties -run


$ bin/oozie job -oozie http://[hostname]:11000/oozie -config oozie-apps/shell/job.properties -run
以上是配置oozie的手动提交 --workflow
