Hi all, In order to track changes who change the behavior of an existing component or break public APIs we could adopt the use of JIRA labels as it is done in other projects.
There are various existing labels used for this purpose in JIRA: * Breaking-Change, * breaking-api, * breaking, * breaking_change, * backwards-incompatible, * backward-incompatible The last one, "backward-incompatible", seems to be the most widely used across projects and in Hive itself so I would suggest sticking to that one and using it consistently. I just updated existing Hive tickets to use "backward-incompatible" and removed the rest mentioned above. I also added a brief mention to the existing guidelines [1]. If you prefer another one that's perfectly fine as well. Best, Stamatis [1] https://cwiki.apache.org/confluence/display/Hive/HowToContribute#HowToContribute-Guidelines
