我是Java的新手,尝试使用Java代码运行Oozie作业时遇到了一些问题。我无法找出代码中的问题,需要帮助。以下是我的代码:
import java.util.Properties;
import org.apache.oozie.client.OozieClient;
import org.apache.oozie.client.WorkflowJob;
public class oozie {
public static void main(String[] args) {
OozieClient wc = new OozieClient("http://host:11000/oozie");
Properties conf = wc.createConfiguration();
conf.setProperty(OozieClient.APP_PATH, "hdfs://cluster/user/apps/merge-psp-logs/merge-wf/workflow.xml");
conf.setProperty("jobTracker", "jobtracker.bigdata.com:8021");
conf.setProperty("nameNode", "hdfs://namenode.bigdata.com:8020");
conf.setProperty("queueName", "jobtracker.bigdata.com:8021");
conf.setProperty("appsRoot", "hdfs://namenode.bigdata.com:8020/user/workspace/apps");
conf.setProperty("appLibLoc", "hdfs://namenode.bigdata.com:8020/user/workspace/lib");
conf.setProperty("rawlogsLoc", "hdfs://namenode.bigdata.com:8020/user/workspace/");
conf.setProperty("mergedlogsLoc", "jobtracker.bigdata.com:8021");
try {
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 (Exception r) {
System.out.println("Errors");
}
}
}
虽然我能够使用命令行启动作业
