> When running single node LLAP with the following query multiple number of
> times (flights table had 7000+ partitions) {{FileUtils.isPathWithinSubtree}}
> became a hotpath.
> {noformat}
> SELECT COUNT(`flightnum`) AS `cnt_flightnum_ok`,
> YEAR(`flights`.`dateofflight`) AS `yr_flightdate_ok`
> FROM `flights` as `flights`
> JOIN `airlines` ON (`uniquecarrier` = `airlines`.`code`)
> JOIN `airports` as `source_airport` ON (`origin` = `source_airport`.`iata`)
> JOIN `airports` as `dest_airport` ON (`flights`.`dest` =
> `dest_airport`.`iata`)
> GROUP BY YEAR(`flights`.`dateofflight`);
> {noformat}
> It would be good to have early exit in {{FileUtils.isPathWithinSubtree}}
> based on path depth comparison.
