Alejandro Abdelnur commented on HDFS-2316:
------------------------------------------
Nicholas,
On #1, sorry don't agree, you are referring to HTTP/1.1 headers. We are talking
about URLs here, except for scheme and host everything else should case
sensitive. Milind has also stated his opinion on this in favor of case
sensitive. Again, this is by spec; still the implementation could be lenient.
On #2, if we go for types, then GETHOMEDIRECTORY uses { "Path" : "<PATH>" },
using similar reasoning GETDELEGATIONTOKEN should return { "Token" : "<TOKEN>"
} (you are skipping the field name of the structure type as the token seems to
treated as an opaque value).
On #3, "symlink" is fine
On #4, then we should state in the parameter 'permission' that is a String with
valid values being a 3 digits octal number or '[0-7][0-7][0-7]'.
On #5, if the Token is to be decoded/parsed by a client in any way, it should
be stated, independent of Hadoop how to do the decoding.
Thanks.

> We current have hftp for accessing HDFS over HTTP. However, hftp is a
> read-only FileSystem and does not provide "write" accesses.
> In HDFS-2284, we propose to have webhdfs for providing a complete FileSystem
> implementation for accessing HDFS over HTTP. The is the umbrella JIRA for
> the tasks.
