Lefty Leverenz commented on HIVE-16982:
---------------------------------------
Doc note: This changes the description of configuration parameter
*hive.log.explain.output*, which is not yet documented in the wiki. It was
introduced in release 1.1.0 by HIVE-8600, and ought to be documented here:
* [Configuration Properties -- Query and DDL Execution |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]
* [Getting Started -- Logs |
https://cwiki.apache.org/confluence/display/Hive/GettingStarted#GettingStarted-ErrorLogs]
* [Language Manual -- Explain |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Explain]
Configuration Properties can give just the new description, since the behavior
isn't changing.
Added a TODOC3.0 label.
> WebUI "Show Query" tab prints "UNKNOWN" instead of explaining configuration

> In the Hive WebUI / Drilldown: the Show Query tab always displays "UNKNOWN."
> If the user wants to see the query plan here, they should set configuration
> hive.log.explain.output to true. The user should be made aware of this option:
> 1) in WebUI / Drilldown / Show Query and
> 2) in HiveConf.java, line 2232.
> This configuration's description reads:
> "Whether to log explain output for every query
> When enabled, will log EXPLAIN EXTENDED output for the query at INFO log4j
> log level."
> this should be added:
> "...and in the WebUI / Show Query tab."
