Description

We are using "yarn.resourcemanager.address" for checking the hadoop version in jobUtils. Here is the code snippet.
// Hadoop 0.20/1.x.

      if (defaultConf.get("yarn.resourcemanager.address") == null) {
          // Duplicate hadoop 1.x code to workaround MAPREDUCE-2361 in Hadoop 0.20
          // Refer OOZIE-1806.
          String filepath = file.toUri().getPath();
          String classpath = conf.get("mapred.job.classpath.files");
          conf.set("mapred.job.classpath.files", classpath == null
              ? filepath
              : classpath + System.getProperty("path.separator") + filepath);
          URI uri = fs.makeQualified(file).toUri();
          DistributedCache.addCacheFile(uri, conf);
      }
      else { // Hadoop 0.23/2.x
          DistributedCache.addFileToClassPath(file, conf, fs);
      }

But this is being used in JavaActionExecutor to set jobTracker.
conf.set(HADOOP_YARN_RM, jobTracker);
