Alejandro Abdelnur commented on HDFS-2316:
------------------------------------------
Regarding case sensitivity, given that HDFS URIs are case sensitive, being case
insensitive in the querystring it would be confusing to users. Furthermore,
being case insensitive in part of the querystring it would be more confusing.
I'd propose we are case sensitive and all params and values we define are
lowercase.
Regarding permissions, you are correct, Hoop uses output style which are
absolute. While uncommon I found the more intuitive. I'll make sure Hoop
handles octal as well.
Regarding file ranges, it is matter of convenience for users. I don't think it
will cause problems because there are not libraries that handle webhdfs/hoop
URLs operations (and use HTTP ranges), users will have to code the
constructions of these URLs and then will use what we provide. Again, I see a
big value if ALL webhdfs/hoop operations are 100% selfcontained in the URL.

> We current have hftp for accessing HDFS over HTTP. However, hftp is a
