org.eclipse.persistence.tools.schemaframework.FieldDefinition
Purpose: Define a database field definition for creation within a table. This differs from DatabaseField in that it is used only table creation not a runtime.
Responsibilities:
- Store the name, java type, size and sub-size. The sizes are optional and the name of the java class is used for the type.

      throw new IllegalArgumentException("Unable to convert data type");
    }


    FieldDefinition definition = convertToFieldDefinition(columnInfo);


    StringWriter writer = new StringWriter();


    try {
      databasePlatform.printFieldTypeSize(writer, definition, fieldType, false); //Ambari doesn't use identity fields
