Milind Bhandarkar commented on HADOOP-1010:
-------------------------------------------
The way I see it, reporter is just another output stream coming out of the
task. It should get a uniform treatment just like other streams. Context is a
good abstraction, since we would be able to hang non-Strings (such as the
task's stream-set) to it.
> getReordReader methof of InputFormat class should handle null reporter
> argument

> In some cases, I need to create a record reader object in the config method
> of mappers.
> At that time, reporter is not available yet. And logically, the reporter
> should not be a required for getRecordReader anyway.
