Allen Wittenauer commented on HADOOP-7307:
------------------------------------------
Hmm. That's sort of surprising. I would have expected the user name to get
resolved to the user that is running the datanode when the built-in auth was
being used. (Doesn't it default to the username of the user running the Java
process everywhere else? Why would it be different for the HDFS web ui?) But
that's also bad for what are hopefully obvious reasons though.
FWIW, in Apache 0.20.2 and prior, we had dfs.web.ugi which looks like it
defaulted to "webuser,webugi".
I'm inclined to think that we likely need to bring this setting back and
default it to either webuser or DrWho. It sounds like the default changed in
0.21, so this is a tricky one.
