[jira] [Commented] (TEZ-1409) Change MRInputConfigurer, MROutputConfigurer to accept specific classes, isntead of a generic class

Bikas Saha commented on TEZ-1409:
---------------------------------

Not sure what this means. They accept a type safe class argument. So one could not pass a committer instead of an output format.
+1 on the Nullable.

> Separate methods to accept either mapred or mapreduce InputFormat. Similarly for the Output. 
> This generates compile time errors while using these methods.
> Ran into this on the first iteration of TEZ-1407, where I had set the wrong class (a committer instead of an OF).
> Also, ideally these should be @Nullable - in case the user has already set them up correctly in the Configuration.
