> Code i have that compiles against HADOOP 2.4 doesn't build against trunk as someone took
away {{DFSConfigKeys.DFS_NAMENODE_USER_NAME_KEY}} -apparently in HDFS-6181.
> I know the name was obsolete, but anyone who has compiled code using that reference -rather
than cutting and pasting in the string- is going to find their code doesn't work.
> More subtly: that will lead to a link exception trying to run that code on a 2.5+  cluster.
> This is a regression: the old names need to go back in, even if they refer to the new
names and are marked as deprecated
