> With security enabled, if one sets up a ViewFS mount table using the default mount table
name, everything works as expected. However, if you try to create a ViewFS mount table with
a non-default name, you'll end up getting an error like the following (in this case "vfs-cluster"
was the name of the mount table) when running an MR job:
> {noformat}
> java.lang.IllegalArgumentException: java.net.UnknownHostException: vfs-cluster
> {noformat}
