Summary: change configuration handling in TezSessionState
Key: HIVE-17431
URL: https://issues.apache.org/jira/browse/HIVE-17431
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
The configuration is only set when opening the session; that seems unnecessary.
E.g. when updating the session and localizing new resources we may
theoretically open the session with a new config, but we don't update the
config and only update the files if the session is already open, which seems to
imply that it's ok to not update the config.
In most cases, the session is opened only once or reopened without intending to
change the config (e.g. if it times out).
