Jason Dere created HIVE-6495:
--------------------------------
Summary: TableDesc.getDeserializer() should use correct
classloader when calling Class.forName()
Key: HIVE-6495
URL: https://issues.apache.org/jira/browse/HIVE-6495
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Reporter: Jason Dere
User is getting an error with the following stack trace below. It looks like
when Class.forName() is called, it may not be using the correct class loader
(JavaUtils.getClassLoader() is used in other contexts when the loaded jar may
be required).
