John Sherman commented on HIVE-22356:
-------------------------------------
FYI this is what is likely causing the randomish test failures in (or some
combination) (I reverted HIVE-22284 after identifying this same issue via code
inspection and it runs reliably locally now):

> After added with HIVE-22284, CacheTag's compareTo() produces wrong result for
> the following edge case and those alike:
> Table name: _dbname.tablename_ PartDesc: _p1=v1_ VS
> Table name: _dbname.tablenamf_ PartDesc: _p1=v0_
> ..due to the addition logic in the method.
