将属性文件传递给 Oozie Java 操作

Question

我设置了一个 Oozie java 操作工作流，我打算使用 Oozie 协调器来安排它。 java 动作运行是一个 Camus Job，我已将其 jar 和属性配置文件放在 workflow/lib 目录中。关于如何将 -P 参数传递给它的任何想法？目前，我正在做这样的事情：

<workflow-app xmlns="uri:oozie:workflow:0.5" name="camus-wf">
    <start to="camusJob"/>
    <action name="camusJob">
        <java>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <configuration>
            <property>
                    <name>mapred.job.name</name>
                    <value>camusJob</value>
                </property>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
            </configuration>
            <main-class>com.linkedin.camus.etl.kafka.CamusJob</main-class>
    <arg>-P</arg>
    <arg>${camusJobProperties}</arg>
        </java>
        <ok to="end"/>
        <error to="fail"/>
    </action>
    <kill name="fail">
        <message>${wf:errorMessage(wf:lastErrorNode())}</message>
    </kill>
    <end name="end"/>
</workflow-app>

camusJobProperties 的样子

hdfs://10.0.2.15:8020/coordCamusJob/workflowAppPath/lib/config.properties

但工作流程似乎并不运行（卡在 PREP 上）。有什么解决办法吗？

谢谢！

编辑：更正我的 nameNode URL 后，我发现我收到以下错误：

所以基本上我的问题是当属性文件位于 HDFS 中时（特别是在 workflow/lib 目录中）我将如何传递属性文件参数

Answer 1

对于问题的第一部分：可能是由于 namenode 或 jobtracker

的 url 不正确

对于第二部分：您必须配置 core-site.xml，属性 fs.defaultFS 到 hdfs://host:port/

此外，在您的 Java 程序中，在您的 config 对象

中设置 core-site.xml 的路径

hadoop

oozie
