                 URL: https://issues.apache.org/jira/browse/REEF-824

            Assignee: Dongjoon Hyun
            Priority: Trivial


To make our code more concise and improve readability, this issue is aiming to replace existing codes with old style type inference.

{code}
-    final Map<Class<? extends T>, Encoder<? extends T>> clazzToEncoderMap =
-        new HashMap<Class<? extends T>, Encoder<? extends T>>();
-    final Map<Class<? extends T>, Decoder<? extends T>> clazzToDecoderMap =
-        new HashMap<Class<? extends T>, Decoder<? extends T>>();
+    final Map<Class<? extends T>, Encoder<? extends T>> clazzToEncoderMap = new HashMap<>();
+    final Map<Class<? extends T>, Decoder<? extends T>> clazzToDecoderMap = new HashMap<>();
{code}
