Review request for hive.
Bugs: HIVE-22284
https://issues.apache.org/jira/browse/HIVE-22284
Repository: hive-git
Description
-------
When keeping track of which buffers correspond to what Hive objects,
CacheContentsTracker relies on cache tags.
Currently a tag is a simple String that ideally holds DB and table name, and a
partition spec concatenated by . and / . The information here is derived from
the Path of the file that is getting cached. Needless to say sometimes this
produces a wrong tag especially for external tables.
Also there's a bug when calculating aggregated stats for a 'parent' tag
(corresponding to the table of the partition) because the overall maxCount and
maxSize do not add up to the sum of those in the partitions. This happens when
buffers get removed from the cache.
