Hi Andrew,
I am sorry to hear that your HADOOP-9418 patch causes a serious bug in
DistributFileSystem, which is a very important client API. How exactly to
audit DFS do you suggest so that it could avoid further bugs? It does seem
that HADOOP-9418 has not been well tested. Do you agree? I do think reverting
HADOOP-9418 may make more sense.
