Description:
This code will fail because folabe value not fold, we should keep result
consistent whether Optimize rule exists or not.

ReorderAssociativeOperator).map(_.ruleName)
withSQLConf(SQLConf.OPTIMIZER_EXCLUDED_RULES.key ->
excludedRules.mkString(",")) {
sql("select approx_count_distinct(1, 0.01 + 0.02)")
}{code}
