> The HostsFileReader silently fails if the includes or excludes files do
> not exist or are not readable. The current behavior is to overwrite the
> existing set of hosts or excluded hosts, regardless of whether or not
> the includes/excludes file exists.
> This behavior was introduced in HADOOP-5643 to support updating the job
> tracker's node lists. The HostsFileReader is no longer used by the job
> tracker. If this behavior was intentional, it no longer seems necessary
> for any reason. The HostsFileReader is still used by NodeListManager as
> well as the DatanodeManager, and in both cases, throwing an exception
> when the include/exclude files aren't found/readable is desirable.
> We should validate the given includes and excludes files before using
> them.
