Karen Coppage commented on HIVE-17268:
--------------------------------------
[~pvary] Thanks very much for your input! That makes a lot of sense, and I made
appropriate fixes.
One clarification: The HiveConf accessible by the jamon file matches the
original configuration; however, if hive.log.explain.output is originally set
to true, it can be turned off and back on again on a per session basis (which
might not be so bad). If it is initially set to false, then turned on within
the session, it should be viewable somewhere in the logs/output, just never on
the WebUI. So the user does have some freedom in this respect.

> The Hive WebUI's Query Plan tab displays "SET hive.log.explain.output TO true
> TO VIEW PLAN" even when hive.log.explain.output is set to true, when the
> query cannot be compiled, because the plan is null in this case.
