Sergey Shelukhin commented on HIVE-18571:
-----------------------------------------
Rebased the patch and updated to fix some tests.
Added AcidUtils method to collect files for stats based on ACID state, that can
be used for analyze queries.
However, I'm not sure it can be used at any other time (e.g. during
insert/create) because current ACID state does not reflect the transaction that
is in progress.
I think we can tackle that in a followup jira, I left a bunch of TODOs.
