@rickysaltzer - I don't have my kerberos hadoop running atm, but here are
some comments:
This variable should be camelCase, rather than ALL_CAPS.
```
private long TICKET_RENEWAL_THRESHOLD_SEC;
```
I think `hdfsResources.set(null);` should probably be
`hdfsResources.set(new HdfsResources(null, null, null);` .. Walking through the
code by hand...won't getUserGroupInformation in getFileSystem NPE when you're
not using kerberos?
Will send more when I have a chance to build and run.
