>             Project: Hadoop YARN

> The getRunAsUser implementation is package private, but there is no comment stating why. 
> * I suggest we open it up so that we can override it without having to write code in a special hadoop namespace.
> Alternatively: 
> * Lets provide a clear comment about why its package private, if there is a good reason. 
> Here is my justification for making the method public. 
> There are certain implementations where we want more nuanced LCE behaviour.  
> In one case, we might want to allow users to override the behaviour of YARN-1235 (i.e. in highly secured clusters) 
> {noformat}
>  getRunAsUser(String u){ return u ; } 
> {noformat} 
> Or maybe I'd want to route different users to different super implementations: 
> {noformat}
> mary,tom,sally -> execute using analytics1
> joe,bob,kim -> execute using analytics2
> jim,cara -> nobody 
> {noformat}
