Alejandro Abdelnur commented on MAPREDUCE-4010:
-----------------------------------------------
The root cause of the failure is that the deprecation logic (to replace old
keys with new keys) has always been wrong as it was breaking iterator(), but
his was never exposed as it was not being used until now. HADOOP-8167 attempts
to fix this in the least intrusive way, still intrusive. We can can 'fix'
size() to return size of the iterator, but that would require building and
iterating the iterator on size().
IMO this is an expensive thing to do, thus the change in this testcase which
verifies the contents of the configuration are the expected ones.
