Navis commented on HIVE-4801:
-----------------------------

Adding some enum type for deprecated configs which can suggest 
alternative('mapred.reduce.tasks.speculative.execution' in this case) would be 
good.

                
> hive.mapred.map.tasks.speculative.execution is not used to configure Hadoop 
> jobs
