[GitHub] gianm opened a new pull request #6600: Expressions: Fix improper supplier reuse with missing columns.

gianm opened a new pull request #6600: Expressions: Fix improper supplier reuse with missing columns.
URL: https://github.com/apache/incubator-druid/pull/6600
 
 
   ExpressionSelectors has an optimization that skips building a Map
   when there is only one input supplier. However, this optimization
   should not be used in the case where the is one input supplier but
   more than one input identifier (which can happen when only one
   input identifier corresponds to an actual column).
   
   Fixes #6556.
