--------------------------------------
[~prongs]
Hi, this patch clarifies to the user that configuration
{noformat}hive.log.explain.output{noformat} is now also responsible for
determining whether the WebUI displays query information, because of your patch
HIVE-13500 where
{noformat}
if (conf.getBoolVar(ConfVars.HIVE_LOG_EXPLAIN_OUTPUT) ||
conf.isWebUiQueryInfoCacheEnabled()) {
{noformat}
became
{noformat}
if (conf.getBoolVar(ConfVars.HIVE_LOG_EXPLAIN_OUTPUT)) {
{noformat}
Would you mind taking a look at this?

> 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."
