Martin Junghanns commented on FLINK-2315:
-----------------------------------------
Hi [~StephanEwen], I checked my 'NormalizableKey & Writable' implementation [1]
against a more complex program involving sorts [2]. The methods actually get
called, so this issue is not valid anymore. And thanks for the clarification of
raw bytes vs. normalizable keys, I will update our code accordingly!

> Hadoop Writables cannot exploit implementing NormalizableKey
> ------------------------------------------------------------
>
> Key: FLINK-2315
> URL: https://issues.apache.org/jira/browse/FLINK-2315
> Project: Flink
> Issue Type: Bug
> Components: DataSet API
> Affects Versions: 0.9
> Reporter: Stephan Ewen
> Fix For: 1.0.0
>
>
> When one implements a type that extends {{hadoop.io.Writable}} and it
> implements {{NormalizableKey}}, this is still not exploited.
> The Writable comparator fails to recognize that.
