godfrey he updated FLINK-14724:
-------------------------------
Description: currently the plan of tpcds q38.sql contains
{{NestedLoopJoin}}, because it's join condition is {{CAST(AND(IS NOT DISTINCT
FROM($2, $3), IS NOT DISTINCT FROM($1, $4), IS NOT DISTINCT FROM($0,
$5))):BOOLEAN}}, and planner can't find equal join keys from the condition by
{{Join#analyzeCondition. {{ SimplifyJoinConditionRule}} could solve this.
