Suresh Srinivas commented on HADOOP-9523:
-----------------------------------------
bq. In this case, however, it was a command line interface...
It is the output of the main right? Irrespective of programmatically or command
line, we need to make sure class is backward compatible. That means method
return values or output cannot change.
bq. Adding "Incompatible Change" for now, so folks are aware of it.
I actually think this is not necessary unless it has appropriate
InterfaceAudience. The whole idea of such classification was to say, if some
thing changes in such classes and if you use it, be ready to change.
