Fabian Hueske commented on FLINK-1180:
--------------------------------------

Have a look at how the wrappers for the mapred API are done.
Maybe you can reuse some of the wrappers for value iterators and output collectors.

> Flink currently supports hadoop mapred mapper and reduce function but not via mapreduce
api. 
> Reference: email exchange on flink mailing list.
> "...Another option would be to extend the Hadoop Compatibility Layer. Right now, we have
wrappers for Hadoop's mapred-API function (Mapper, Reducer), but not for the mapreduce-API
functions [2]. Having wrappers for mapreduce-API functions would also be cool. There is no
JIRA for this issue yet. "
