Phabricator updated HIVE-2872:
------------------------------
Attachment: HIVE-2872.D2337.1.patch
kevinwilfong requested code review of "HIVE-2872 [jira] Store which configs the
user has explicitly changed".
Reviewers: JIRA
https://issues.apache.org/jira/browse/HIVE-2872
Config variables which are set by System properties, the hiveconf option on
the CLI, and the SET command within the CLI, are recorded by the SessionState
in a new variable
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.
