Store which configs the user has explicitly changed
---------------------------------------------------
Key: HIVE-2872
URL: https://issues.apache.org/jira/browse/HIVE-2872
Project: Hive
Issue Type: Improvement
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
It would be useful to keep track of which config variables the user has
explicitly changed from the values which are either default or loaded from
hive-site.xml. These include config variables set using the hiveconf argument
to the CLI, and via the SET command. This could be used to prevent Hive from
changing a config variable which has been explicitly set by the user, and also
potentially for logging to help with later debugging of failed queries.
