> If the directory for a Hive table could not be created, them the HMS will throw a metaexception:
> {code}
>  if (tblPath != null) {
>           if (!wh.isDir(tblPath)) {
>             if (!wh.mkdirs(tblPath, true)) {
>               throw new MetaException(tblPath
>                   + " is not a directory or unable to create one");
>             }
>             madeDir = true;
>           }
>         }
> {code}
> However in the finally block we always try to call the DbNotificationListener, which
in turn will also throw an exception because the directory is missing, overwriting the initial
exception with a FileNotFoundException.
> Actual stacktrace seen by the caller:
