Oozie workflow - invoked from Java using Oozie Java API
import java.util.Properties;

public class myOozieWorkflowJavaAPICall {
public static void main(String[] args) {
OozieClient wc = new OozieClient("http://cdh-dev01:11000/oozie");
Properties conf = wc.createConfiguration();
conf.setProperty("nameNode", "hdfs://cdh-nn01.chuntikhadoop.com:8020");
conf.setProperty("jobTracker", "cdh-jt01:8021");
conf.setProperty("queueName", "default");
conf.setProperty("oozie.libpath", "${nameNode}/user/oozie/share/lib");

conf.setProperty(OozieClient.APP_PATH, "${appPath}");
conf.setProperty("inputDir", "${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());
}
}
}
To run this sample:
1. You need to have installed code from my blog on the Oozie java mail action-
