@revans2 I added caching to ShellBasedUnixGroupsMapping class using
TimeCacheMap with a config option. I removed caching related apis from the
interface as you suggested didn't feel they are useful while implementing the
above caching.
Is it ok if I do the merge for ShellProcess and ShellUtils in another JIRA.

> It would really be great if authentication for topology access, and the UI

> It might be worth looking at some Hadoop code that already does things like
