Oozie调用Spark实例

看了 http://www.cnblogs.com/en-heng/p/5531583.html 工作流引擎Oozie（一）：workflow  这篇博客后对本文做出如下修改:

oozie调用spark有三样是必须有的: workflow.xml(不可改名) , job.properties(可改名) , jar包(自备).

 1.workflow.xml

<workflow-app  name="Spark-example2" xmlns="uri:oozie:workflow:0.5">  
    <start to="SparkOozieAction1"/>  
    <action name="SparkOozieAction1">
        <spark xmlns="uri:oozie:spark-action:0.1">  
            <job-tracker>${jobTracker}</job-tracker>  
            <name-node>${nameNode}</name-node>
            <configuration>  
                <property>  
                    <name>mapred.job.queue.name</name>  
                    <value>${queueName}</value>  
                </property>                  
            </configuration>            
            <master>yarn-cluster</master>
            <mode>cluster</mode>
            <name>Spark Example1</name>
            <class>com.ocn.itv.rinse.ErrorCollectRinse</class>            
            <jar>ocn-itv-spark-3.0.3-rc1.jar</jar> 
            <spark-opts>${sparkopts}</spark-opts> 
            <arg>${input1}</arg>            
        </spark > 
        <ok to="end"/>
        <error to="kill"/>    
    </action>  
    <kill name="kill">  
        <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>  
    </kill>  
    <end name="end"/>  
</workflow-app>

 workflow.xml需要放到hdfs中.

Oozie支持Spark action，不过支持的不是特别好。提交spark任务时，需要加载spark-assembly jar。在job.properties中设置 oozie.use.system.libpath=True即可加载加载用户lib库(oozie的system share lib)中相关的jar包.

2.job.properties

nameNode=hdfs://hgdp-001:8020    --HDFS文件系统的端口
jobTracker=hgdp-001:8032   resourceManager的端口
queueName=default    --oozie队列
input1=2017-05-09    --要输入的参数
hdfspath=user/root  --自定义路径
examplesRoot=ocn-itv-oozie    ---全局目录
oozie.use.system.libpath=True　　
sparkopts=--executor-memory 1G    --是否加载用户lib库(oozie的system share lib)
oozie.libpath=${nameNode}/${hdfspath}/${examplesRoot}/lib/    用户自定义lib库(存放所需jar包)
oozie.wf.application.path=${nameNode}/${hdfspath}/${examplesRoot}/wf/wf2/   --workflow.xml在hdfs中的地址

job.properties放在本地目录中即可.

3.运行: oozie job -config job.properties -run -oozie http://xxx(地址):11000/oozie
