Konstantin Boudnik commented on HADOOP-6944:
--------------------------------------------
Yup, I think that's it.
One nit:
- would it be better to throw NoSuchMethodException from the body of default
{{writeToFile}} implementation here
{noformat}
+ ProxyUserDefinitions pud = new ProxyUserDefinitions() {
+ public boolean writeToFile(URI filePath) throws IOException {
+ return false;
+ };
{noformat}
Other than that it looks good.
> [Herriot] Implement a functionality for getting proxy users definitions like
> groups and hosts.

> Gridmix should require a proxy user's file for impersonating various jobs.
> So, implement couple of methods for getting the proxy users list and a proxy
> users file (it's a combination of proxy users and groups) based on cluster
> configuration.
> The proxy users list should require for map reduce jobs and proxy users file
> should require for gridmix jobs.
> The following are methods signature,
> public ProxyUserDefinitions getHadoopProxyUsers() - get the list of proxy
> users list based on cluster configuration.
