Eli Collins commented on HDFS-3733:
-----------------------------------
Andy, looking good!
- In FSN#getFileInfo why catch UnresolvedLinkException and StandbyException,
just AccessControlException is sufficient right?
- Nit, I'd remove the System.out.printlns for debugging in the tests?
- Per jenkins there's a javadoc warning:
{noformat}
