我们使用clouderacdh5.4.0，并一直试图从javaapi触发oozie作业来发送电子邮件。使用smtp登录发送的电子邮件依赖于两个第三方jar文件-activation.jar和mail.jar。当第三方文件放在文件系统的同一文件夹中时，java程序可以从ide/jar文件包发送电子邮件。
但是，当我们将文件移动到hdfs并尝试配置oozie作业时，它无法完成。
我们的oozie作业xml如下（email.xml）：

<workflow-app name="Email" xmlns="uri:oozie:workflow:0.5">
    <start to="java-95a1"/>
    <kill name="Kill">
        <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <action name="java-95a1">
        <java>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <main-class>org.Emails</main-class>
             <java-opts>[{u&#39;value&#39;: u&#39;&#39;}]</java-opts>
        </java>
        <ok to="End"/>
        <error to="Kill"/>
    </action>
    <end name="End"/>
</workflow-app>

作业属性为：

nameNode=hdfs://localhost:8020
jobTracker=localhost:8021
queueName=default
weatherRoot=weather_ooze
mapreduce.jobtracker.kerberos.principal=foo
dfs.namenode.kerberos.principal=foo
oozie.libpath=${nameNode}/user/oozie/share/lib
oozie.wf.application.path=${nameNode}/user/${user.name}/${weatherRoot}
outputDir=weather-ooze

这些文件放置在hdfs文件夹中，如下所示：
/user/oozie/ooziewfconfigs/emailappdef/emailjavaprogram.jar/user/oozie/ooziewfconfigs/emailappdef/email.xml/user/oozie/ooziewfconfigs/emailappdef/job.properties/user/oozie/ooziewfconfigs/emailappdef/lib/activation.jar/user/oozie/ooziewfconfigs/emailappdef/lib/mail.jar
在一个论坛里读到，放在lib文件夹中的jar文件将被自动拾取。
oozie作业使用java api触发，如下所示：

import java.util.Properties;

import org.apache.oozie.client.OozieClient;
import org.apache.oozie.client.WorkflowJob;

public class oozieclient {

    public static void main(String[] args) {
        OozieClient wc = new OozieClient("http://hdfs:hdfs@172.16.142.124:11000/oozie");

        Properties conf = wc.createConfiguration();

        conf.setProperty("nameNode", "hdfs://kwt-dev-hdpdn6.hadoop.local:8020");
        conf.setProperty("jobTracker", "kwt-dev-hdpdn6.hadoop.local:8032");
        conf.setProperty("queueName", "default");
        conf.setProperty("oozie.libpath", "${nameNode}/user/oozie/OozieWFConfigs/emailAppDef/lib");
        conf.setProperty("oozie.use.system.libpath", "true");
        conf.setProperty("oozie.wf.rerun.failnodes", "true");

        conf.setProperty("oozieProjectRoot",
                "${nameNode}/user/oozie");
        conf.setProperty("appPath",
                "${oozieProjectRoot}/OozieWFConfigs/emailAppDef");
        conf.setProperty(OozieClient.APP_PATH, "${appPath}/email.xml");

        // conf.setProperty("inputDir", "${oozieProjectRoot}/data/*/*/*/*/*");
        conf.setProperty("outputDir", "${appPath}/output");

        try {
            String jobId = wc.run(conf);
            System.out.println("Workflow job, " + jobId + " submitted");

            while (wc.getJobInfo(jobId).getStatus() == WorkflowJob.Status.RUNNING) {
                System.out.println("Workflow job running ...");
                Thread.sleep(10 * 1000);
            }
            System.out.println("Workflow job completed ...");
            System.out.println(wc.getJobInfo(jobId));
        } catch (Exception r) {
            System.out.println("Errors " + r.getLocalizedMessage());
        }
    }
}

作业被触发时，会一直运行到33%-50%，然后挂起。既不终止也不继续。有人能帮我吗？我不能在oozie中使用默认的电子邮件进程，因为我需要在这封电子邮件工作后添加附件。我希望它能从使用activation.jar和email.jar的java程序中工作。
作业触发时，配置如下：
应用程序路径hdfs://kwt-dev-hdpdn6.hadoop.local：8020/user/oozie/ooziewfconfigs/emailappdef
jobtracker kwt-dev-hdpdn6.hadoop。local:8032
