> DFSUtil#substituteForWildcardAddress subs in a default hostname if the given hostname
is 0.0.0.0. However, this function throws an exception if the given hostname is set to 0.0.0.0
and security is enabled, regardless of whether the default hostname is also 0.0.0.0. This
function shouldn't throw an exception unless both addresses are set to 0.0.0.0.
