my java code as follow:
System.setProperty("java.security.auth.login.config", System.getProperty("user.dir") + File.separator + "conf"
+ File.separator + "jaas.conf ");
System.setProperty("java.security.krb5.conf", System.getProperty("user.dir") + File.separator + "conf"
+ File.separator + "krb5.conf ");
String url = "https://10.137.60.60:21003/oozie";
AuthOozieClient wc = new AuthOozieClient(url);
wc.setDebugMode(1);
Properties conf = wc.createConfiguration();
FileReader fr = new FileReader("conf/job.properties");
conf.load(fr);
System.out.println(conf.toString());
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(3 * 1000);
}
System.out.println("Workflow job completed ...");
System.out.println(wc.getJobInfo(jobId));
my conf/jaas.conf as follow:
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
keyTab="D:/workspace/4.4-billing/Oozie/conf/oozie.keytab"
principal="oozie#HADOOP.COM"
useTicketCache=false
storeKey=true
debug=true;
};
can anyone help me ? I know oozie use hadoop-auth jar. but how to set keytab, write authenticate code, I cannot.

set your kerberos user account as
conf.setProperty(OozieClient.USER_NAME, "xyz");
oozieClient.run(conf);
