> 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 String getProxyUsersFile() - getting the proxy users file based on 
> cluster configuration information.
> public String buildProxyUsersFile() - Build the proxy users file using the 
> cluster configuration.
> public ArraryList<String> getHadoopMultiUsersList() - get the list of proxy 
> users list based on cluster configuration.
