Class Summary

Class	Description
Bug	Holder for a list of constants describing which bugs have not been fixed.
HiveCalciteUtil	Generic utility functions needed for Calcite based Hive CBO.
HiveCalciteUtil.ConstantFinder	Walks over an expression and determines whether it is constant.
HiveCalciteUtil.FixNullabilityShuttle	Shuttle that fixes up an expression to match changes in nullability of input fields.
HiveCalciteUtil.JoinLeafPredicateInfo	JoinLeafPredicateInfo represents leaf predicate in Join condition (conjuctive lement).
HiveCalciteUtil.JoinPredicateInfo	JoinPredicateInfo represents Join condition; JoinPredicate Info uses JoinLeafPredicateInfo to represent individual conjunctive elements in the predicate. JoinPredicateInfo = JoinLeafPredicateInfo1 and JoinLeafPredicateInfo2...
