> The cache introduced in HIVE-22825 is not invalidated in TezAMs which can
> eventually lead to query failures if the same table is used in a scenario
> like below:
> 1. CREATE TABLE
> 2. INSERT OVERWRITE
> 3. SELECT
> 4. DROP TABLE
> ...
> in this case if 2) wrote a file like year=2011/base_0000001/bucket_00000_*1*
> (task attempt = 1), and in the next iteration it wrote
> year=2011/base_0000001/bucket_00000_*0* (task attempt = 0), then acid
> dirCache contains an invalid value within the configured time range
> *hive.txn.acid.dir.cache.duration*
