Jaydeep Vishwakarma commented on OOZIE-2074:
--------------------------------------------

Checking the "yarn.resourcemanager.webapp.address" property will be fine instead of "yarn.resourcemanager.address".

> 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);
