Description

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:

java.lang.IllegalArgumentException: java.net.UnknownHostException: vfs-cluster
