Pavel Semenov commented on DRILL-6974:
--------------------------------------
*Check List*
1) Check set `drill.exec.hashagg.fallback.enabled` -> shows current value
2) Check set `drill.exec.hashagg.fallback.enabled` = true/false -> updates
property value
3) Check show `drill.exec.hashagg.fallback.enabled` -> should not work
4) Check that it works with different properties
5) Check ALTER SESSION / SYSTEM options
Verified in master branch on v 1.17.0 . *All cases passed successfully*

> Key: DRILL-6974
> URL: https://issues.apache.org/jira/browse/DRILL-6974
> Project: Apache Drill
> Issue Type: Improvement
> Components: SQL Parser
> Affects Versions: 1.15.0
> Reporter: benj
> Assignee: Dmytriy Grinchenko
> Priority: Major
> Labels: doc-impacting, ready-to-commit
> Fix For: 1.17.0
>
>
> It's currently possible to define options with the SQL command SET
> {code:java}
> ALTER SESSION SET `drill.exec.hashagg.fallback.enabled` = true;
> {code}
> But it's not possible to simply visualize the current value of one option
> with SHOW, we have to query like
> {code:java}
> SELECT * FROM sys.options WHERE `name` =
> 'drill.exec.hashagg.fallback.enabled';
> {code}
> Why not allow a simple
> {code:java}
> SET `drill.exec.hashagg.fallback.enabled`;
> {code}
