java - 使用Java代码启动oozie作业

Question

我正在尝试使用javacode启动oozie作业，但无法执行相同操作。以下代码为几行代码提供了异常“unhandled type oozieClientException”

String jobId = wc.run(conf);

我是Java新手，正在寻求帮助。这是我的代码:

    OozieClient wc = new OozieClient("http://host.com:11000/oozie");

    Properties conf = wc.createConfiguration();
    conf.setProperty(....)
    ...
    String jobId = wc.run(conf);
    System.out.println("Workflow job 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)); 

Answer 1

您应该在try catch块中关闭代码

try{
    OozieClient wc = new OozieClient("http://host.com:11000/oozie");

    Properties conf = wc.createConfiguration();
    conf.setProperty(....)
    ...
    String jobId = wc.run(conf);
    System.out.println("Workflow job 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(OozieClientException oozieClientException){
    oozieClientException.printStackTrace();
}

OozieClientException-如果无法提交作业，则引发
