[jira] [Commented] (HIVE-8785) HiveServer2 LogDivertAppender should
be more selective for beeline getLogs
[ https://issues.apache.org/jira/browse/HIVE-8785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14245887#comment-14245887 ]
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.

> A more complex query like Query27 produces 800+ lines of unnecessary logging.
> This is unreadable and in-fact slows down the beeline JDBC client.
