> YARN-1824 broke compatibility with previous 2.x releases by changes the API's 
> in org.apache.hadoop.yarn.util.Apps.{setEnvFromInputString,addToEnvironment}  
> The old api should be added back in.
> This affects any ApplicationMasters who were using this api.  It also breaks 
> previously built MapReduce libraries from working with the new Yarn release 
> as MR uses this api.
