----------------------------------

Hi [~fhueske] sorry I did provide enough description about this issue. I have added more information. 

About your last question, yes, your idea can also implement it. However, that means user
need extends a subclass of Mapper right? Here, I think a good experience is to let the old
program (MapReduce program written by Hadoop new MapReduce API) keep the least changes. What
do you think? If we use reflection, we only need to get it once.

> Currently, Flink only support {{org.apache.flink.hadoopcompatibility.mapred.Mapper}}
in module flink-hadoop-compatibility. I think we also need to support Hadoop new Mapper API
: {{org.apache.hadoop.mapreduce.Mapper}}.
