László Bodor updated HIVE-27328:
--------------------------------
Description:
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) write 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
> Acid dirCache is not invalidated in TezAMs while dropping table
