---------------------------
Summary: getRunAsUser should be overridable (outside of package) (was:
getRunAsUser should be overridable )
> getRunAsUser should be overridable (outside of package)
> --------------------------------------------------------
>
> Key: YARN-1952
> URL: https://issues.apache.org/jira/browse/YARN-1952
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Reporter: jay vyas
>
> 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}
