Namit Jain created HIVE-3410:
--------------------------------
Summary: All operators's conf should inherit from a common class
Key: HIVE-3410
URL: https://issues.apache.org/jira/browse/HIVE-3410
Project: Hive
Issue Type: Improvement
Reporter: Namit Jain
I faced this problem while working on HIVE-3086.
Wanted to add a common interface to all the operator's confs.
Currently, the operator signature is Operator<T extends Serializable>,
which makes it difficult to add more methods to T.
Created a common interface SerializableCloneable, and now
Operator<T extends SerializableCloneable>.
If we want to add more methods to SerializableCloneable in the future,
it wont require changing so many files, so submitting it as a separate patch.
