Stephan Ewen commented on FLINK-2315:
-------------------------------------
I think this is pretty easy to fix.
The {{WritableComparator}} needs to check if the type implements the
{{NormalizableKey}} interface.
https://github.com/apache/flink/blob/master/flink-java/src/main/java/org/apache/flink/api/java/typeutils/runtime/WritableComparator.java
As an example, check out the {{ValueComparator}} which does exactly that:

> Hadoop Writables cannot exploit implementing NormalizableKey

> Project: Flink
> Issue Type: Bug

> When one implements a type that extends {{hadoop.io.Writable}} and it
