hao created HIVE-24115:
--------------------------
Summary: Kryo's instantiation strategy should use the
DefaultInstantiatorStrategy instead of the dangerous StdInstantiatorStrategy
Key: HIVE-24115
URL: https://issues.apache.org/jira/browse/HIVE-24115
Project: Hive
Issue Type: Wish
Reporter: hao
DefaultInstantiatorStrategy is the recommended way of creating objects with
Kryo. It runs constructors just like would be done with Java code. Alternative,
extralinguistic mechanisms can also be used to create objects. The
[Objenesis|http://objenesis.org/] StdInstantiatorStrategy uses JVM specific
APIs to create an instance of a class without calling any constructor at all.
Using this is dangerous because most classes expect their constructors to be
called. Creating the object by bypassing its constructors may leave the object
in an uninitialized or invalid state. Classes must be designed to be created in
this way.
