             Summary: Mapreduce mini cluster using HBaseTestingUtility not setting correct resourcemanager and jobhistory webapp address of MapReduceTestingShim  
                 Key: HBASE-16375
                 URL: https://issues.apache.org/jira/browse/HBASE-16375
             Project: HBase
          Issue Type: Bug
            Reporter: Loknath Priyatham Teja Singamsetty 
            Assignee: Loknath Priyatham Teja Singamsetty 


Starting mapreduce mini cluster using HBaseTestingUtility is not setting "yarn.resourcemanager.webapp.address" and "mapreduce.jobhistory.webapp.address" which are required for getting the submitted yarn apps using mapreduce webapp. These properties are not being copied from jobConf of MapReduceTestingShim resulting in default values.

HBaseTestingUtility.java
    // Allow the user to override FS URI for this map-reduce cluster to use.
    mrCluster = new MiniMRCluster(servers,
      FS_URI != null ? FS_URI : FileSystem.get(conf).getUri().toString(), 1,
      null, null, new JobConf(this.conf));
    JobConf jobConf = MapreduceTestingShim.getJobConf(mrCluster);
    if (jobConf == null) {
      jobConf = mrCluster.createJobConf();
    }

    jobConf.set("mapreduce.cluster.local.dir",
      conf.get("mapreduce.cluster.local.dir")); //Hadoop MiniMR overwrites this while it should not
    LOG.info("Mini mapreduce cluster started");

    // In hadoop2, YARN/MR2 starts a mini cluster with its own conf instance and updates settings.
    // Our HBase MR jobs need several of these settings in order to properly run.  So we copy the
    // necessary config properties here.  YARN-129 required adding a few properties.
    conf.set("mapreduce.jobtracker.address", jobConf.get("mapreduce.jobtracker.address"));
    // this for mrv2 support; mr1 ignores this
    conf.set("mapreduce.framework.name", "yarn");
    conf.setBoolean("yarn.is.minicluster", true);
    String rmAddress = jobConf.get("yarn.resourcemanager.address");
    if (rmAddress != null) {
      conf.set("yarn.resourcemanager.address", rmAddress);
    }
    String historyAddress = jobConf.get("mapreduce.jobhistory.address");
    if (historyAddress != null) {
      conf.set("mapreduce.jobhistory.address", historyAddress);
    }
    String schedulerAddress =
      jobConf.get("yarn.resourcemanager.scheduler.address");
    if (schedulerAddress != null) {
      conf.set("yarn.resourcemanager.scheduler.address", schedulerAddress);
    }
{quote}

As a immediate fix for phoenix e2e test to succeed, need the below lines to be added as well
{quote}
    String rmWebappAddress = jobConf.get("yarn.resourcemanager.webapp.address");
    if (rmWebappAddress != null) {
      conf.set("yarn.resourcemanager.webapp.address", rmWebappAddress);
    }
    String historyWebappAddress = jobConf.get("mapreduce.jobhistory.webapp.address");
    if (historyWebappAddress != null) {
      conf.set("mapreduce.jobhistory.webapp.address", historyWebappAddress);
    }
{quote}

Eventually, we should also see if we can copy over all the jobConf properties to HBaseTestingUtility conf object.
