> The {{LocalFileSystem}} returns file splits with a host information as returned via
> {code}
> InetAddress.getLocalHost().getHostName();
> {code}
> This might be different, though, from the host name that the TaskManager is configured to use, which results in incorrect location matching if this information is used.
> It is also incorrect in cases where the file system is in fact not local, but a mounted NAS.
> Since this information is anyways not useful (there no good way to support locality-aware file access for the LocalFileSystem) I would suggest to remove this code. That would be better than having code in place that tries to suggest locality information that is frequently incorrect.
