             Summary: Create a set of builders for Thrift classes
                 Key: HIVE-17981
                 URL: https://issues.apache.org/jira/browse/HIVE-17981
             Project: Hive
          Issue Type: Sub-task
          Components: Standalone Metastore
            Reporter: Alan Gates
            Assignee: Alan Gates
            Priority: Major


Instantiating some of the Thrift classes is painful.  Consider building a {{Table}} object, which requires a {{StorageDescriptor}}, which requires a {{SerDeInfo}} and a list of {{FieldInfo}}.  All that is really necessary for a Table in the most simple case is a name, a database, and some columns.  But currently creating even a simple Table requires 20+ lines of code.  This is particularly painful in tests.  

I propose to add a set of builders.  These will come with reasonable defaults to minimize the boilerplate code.  They will also include simple methods for common operations (like adding columns, or a parameter) without requiring the user to create all the sub-objects (like {{StorageDescriptor}}).
