-----------------------------------------
[~xuefuz] i've fixed another intresting subdirectory related method during
HIVE-12244; that one i think matched '/backup/foo/bar' as a parent of '/foo'
https://github.com/apache/hive/commit/47b5b5cdb8702c9ddbca3911b6a03ca59982b3c1#diff-c39d962bbd4b5ca645cfb9275b899a68L593
[~lirui] the only "user" of this {{FileUtils::isSubDir}} method is {{Hive}},
it would be better to move this method there too? ...or...at first blink it
seems like the only uses of these methods are originating from
{{MoveTask}}...and these operations seem to be independent from the
{{Hive::hiveDB}} threadlocal...
> FileUtils.isSubDir may return incorrect result
