Example 10 with ApplicationMasterProtocol

use of org.apache.hadoop.yarn.api.ApplicationMasterProtocol in project hadoop by apache.

the class TestUnmanagedAMLauncher method main.

// provide main method so this class can act as AM
public static void main(String[] args) throws Exception {
    if (args[0].equals("success")) {
        ApplicationMasterProtocol client = ClientRMProxy.createRMProxy(conf, ApplicationMasterProtocol.class);
        client.registerApplicationMaster(RegisterApplicationMasterRequest.newInstance(NetUtils.getHostname(), -1, ""));
        Thread.sleep(1000);
        FinishApplicationMasterResponse resp = client.finishApplicationMaster(FinishApplicationMasterRequest.newInstance(FinalApplicationStatus.SUCCEEDED, "success", null));
        assertTrue(resp.getIsUnregistered());
        System.exit(0);
    } else {
        System.exit(1);
