Subject [jira] [Commented] (HIVE-16653) Mergejoin should give itself a correct tag
Date Wed, 31 May 2017 18:25:04 GMT

Ashutosh Chauhan commented on HIVE-16653:
-----------------------------------------

[~pxiong] Can you describe the problem little more here? As I see it, you are updating tag
of merge work even when this rule doesnt alter anything in plan. That doesnt seem correct.

Was it the case that tag was not set at all on that merge work. If so, than it should have
been set when it was created. If it was set, then there shouldnt be a need to update it in
this rule, since you are updating it when rule doesnt alter the plan at all.
