--------------------------------------
Summary: get rid of pre-optimized-hashtable memory optimizations
Key: HIVE-9331
URL: https://issues.apache.org/jira/browse/HIVE-9331
Project: Hive
Issue Type: Bug
Affects Versions: 0.15.0
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
These were added in 13 because optimized hashtable couldn't make it in; they
reduced memory usage by some amount (10-25%), and informed the design of the
optimized hashtable, but now extra settings and code branches are just
confusing and may have their own bugs. Might as well remove them.
