> 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}
