----------------------------------------------
Summary: Add method to compare Operators
Key: HIVE-16945
URL: https://issues.apache.org/jira/browse/HIVE-16945
Project: Hive
Issue Type: Improvement
Components: Operators
Affects Versions: 3.0.0
Reporter: Jesus Camacho Rodriguez
HIVE-10844 introduced a comparator factory class for operators that
encapsulates all the logic to assess whether two operators are equal:
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/OperatorComparatorFactory.java
The current design might create problems as any change in fields of operators
will break the comparators. It would be better to do this via inheritance from
Operator base class, by adding a {{compareTo(Operator other)}} method.
