Description

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)

Unknown macro: { 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)

Unknown macro: { conf.set("yarn.resourcemanager.address", rmAddress); }

String historyAddress = jobConf.get("mapreduce.jobhistory.address");
if (historyAddress != null)

Unknown macro: { conf.set("mapreduce.jobhistory.address", historyAddress); }

String schedulerAddress =
jobConf.get("yarn.resourcemanager.scheduler.address");
if (schedulerAddress != null)

Unknown macro: { conf.set("yarn.resourcemanager.scheduler.address", schedulerAddress); }

As a immediate fix for phoenix e2e test to succeed, need the below lines to be added as well

String rmWebappAddress = jobConf.get("yarn.resourcemanager.webapp.address");
if (rmWebappAddress != null)

Unknown macro: { conf.set("yarn.resourcemanager.webapp.address", rmWebappAddress); }

String historyWebappAddress = jobConf.get("mapreduce.jobhistory.webapp.address");
if (historyWebappAddress != null)

Unknown macro: { conf.set("mapreduce.jobhistory.webapp.address", historyWebappAddress); }

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