Andrew Wang commented on HADOOP-13139:
--------------------------------------
Given this is an incompatible change we're targeting for branch-2 (and we're
sure we really want to go through with this), I'd also like to see a log WARN
if the removed config key is set, explaining what to configure instead. That'd
be a good improvement even for trunk too.
