----------------------------------
Summary: Internally used variables in HiveConf should not be
settable via command
Key: HIVE-12346
URL: https://issues.apache.org/jira/browse/HIVE-12346
Project: Hive
Issue Type: Bug
Components: Configuration
Affects Versions: 1.2.1
Reporter: Chaoyu Tang
Assignee: Chaoyu Tang
Some HiveConf variables such as hive.added.jars.path are only for internal use
and should not be settable via set command.
We saw a lot of cases that users mistakenly set these variables using set
command despite some of them have been documented as "internal parameter" in
Hive. The command usually succeeds but it sometimes does not effect, which
causes some confusions. For example, the hive.added.jars.path can be set via
set command but it is sometimes overridden by session resource jars during
runtime.
