+ * For customized type of the following enums, it will try to find declared
class in classpath
+ * and fallback to exception if ClassNotFound. This way the sizeEstimator
and packer could be easier to
+ * extend. The major purpose for keeping this enum instead of using
reflection only to construct the instance
+ * of packer or sizeEstimator is to maintain backward-compatibility.
+ *
+ * The constructor of customized type needs to be annotated with public
access-modifier as it is instantiated by
+ * {@link GobblinConstructorUtils} which reside in different package, and it
needs to have the same signature
+ * as other implementation under the enum.
