Lefty Leverenz commented on HIVE-8785:
--------------------------------------
Doc done: *hive.server2.logging.operation.enabled* and
*hive.server2.logging.operation.verbose* are documented in the wiki.
* [hive.server2.logging.operation.enabled |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.logging.operation.enabled]
* [hive.server2.logging.operation.verbose |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.logging.operation.verbose]
Some guidance about how to use them could be added to one of the HiveServer2
docs (probably Setting Up HS2), with links to & from the logging section in
Getting Started. If that is not needed, the TODOC14 label can be removed.

> This is unreadable and in-fact slows down the beeline JDBC client.
