Eric Payne commented on MAPREDUCE-2874:
---------------------------------------

* I removed the {{Apps.toString(ApplicationId id)}} method from 
o.a.h.yarn.util.Apps.java
* The {{Apps.toString(ApplicationId id)}} method was used by {{webapp}} APIs.
* Since this {{toString}} method has an {{ApplicationId}} as it's parameter, I 
replaced every call to {{Apps.tostring(ApplicationId id)}} with a call to 
{{ApplicationId.toString()}}.
* The result is that in the yarn UI pages, job names now have the form 
application&#95;<epoch>&#95;<job num> rather than app&#95;<epoch>&#95;<job num>

> Looks like the ApplicationId is now printed in 2 different formats.  
> ApplicationIdPBImpl.java has a toString routine that prints it in the format: 
> return "application_" + this.getClusterTimestamp() + "_" + this.getId();
> While the webapps use 
> ./hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/util/Apps.java 
> toString that prints it like:     
> return _join("app", id.getClusterTimestamp(), id.getId());
