Hadoop is not showing my job in the job tracker even though it is running

Question

Problem: When I submit a job to my hadoop 2.2.0 cluster it doesn't show up in the job tracker but the job completes successfully. By this I can see the output and it is running correctly and prints output as it is running.

I have tried muliple options but the job tracker is not seeing the job. If I run a streaming job using the 2.2.0 hadoop it shows up in the task tracker but when I submit it via the hadoop-client api it does not show up in the job tracker. I am looking at the ui interface on port 8088 to verify the job

Environment OSX Mavericks, Java 1.6, Hadoop 2.2.0 single node cluster, Tomcat 7.0.47

Code

    try {
        configuration.set("fs.defaultFS", "hdfs://127.0.0.1:9000");
        configuration.set("mapred.jobtracker.address", "localhost:9001");

        Job job = createJob(configuration);
        job.waitForCompletion(true);
    } catch (Exception e) {
        logger.log(Level.SEVERE, "Unable to execute job", e);
    }

    return null;

The resolution to the issue was to configure the job with the extra configuration options for yarn. I made int incorrect assumption that the java hadoop-client api would use the configuration options from the configuration directory. I was able to diagnose the problem by turning on verbose logging using log4j.properties for my unit tests. It showed that the jobs were running local and not being submitted to the yarn resource manager. With a little bit of trial and error I was able to configure the job and have it submitted to the yarn resource manager.

Code

    try {
        configuration.set("fs.defaultFS", "hdfs://127.0.0.1:9000");
        configuration.set("mapreduce.jobtracker.address", "localhost:54311");
        configuration.set("mapreduce.framework.name", "yarn");
        configuration.set("yarn.resourcemanager.address", "localhost:8032");

        Job job = createJob(configuration);
        job.waitForCompletion(true);
    } catch (Exception e) {
        logger.log(Level.SEVERE, "Unable to execute job", e);
    }

I see that you are using Hadoop 2.2.0. Are you using MRv1 or MRv2? The daemons are different for MRv2 (YARN). There is no JobTracker for MRv2, though you may see a placeholder page for the JobTracker UI.

The ResourceManager web UI should display your submitted jobs. The default web URL for the ResourceManager is http://<ResourcemanagerHost>:8088

Replace ResourceManagerHost with the IP address of the node where the Resource Manager is running.
