Gregory Chanan commented on HADOOP-10911:
-----------------------------------------
bq. on the quotes, we had them, they got removed, that broke things, we added
again. They don't do any harm if they are there.
It's a little more complicated -- HADOOP-10379 made multiple changes like
removing the quotes and the Version field. So it was the combination of
changes that broke things, not specifically removing the quotes.
bq. On Max-Age & Expired, i don't think we want to break old browsers. It seems
to me an HttpClient bug that uses the presence of Expire to go back to old
cookie format, the precense of Version=1 should trump. Can you dig on
HttpClient side?
Seems reasonable, I'll dig.

> I'm seeing the same problem reported in HADOOP-10710 (that is, httpclient is
> unable to authenticate with servers running the authentication filter), even
> with HADOOP-10710 applied.
> From my reading of the spec, the problem is as follows:
> Expires is not a valid directive according to the RFC, though it is mentioned
> for backwards compatibility with netscape draft spec. When httpclient sees
> "Expires", it parses according to the netscape draft spec, but note from
> RFC2109:
> {code}
> Note that the Expires date format contains embedded spaces, and that "old"
> cookies did not have quotes around values.
> {code}
> and note that AuthenticationFilter puts quotes around the value:
> https://github.com/apache/hadoop-common/blob/6b11bff94ebf7d99b3a9e513edd813cb82538400/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/server/AuthenticationFilter.java#L437-L439
> So httpclient's parsing appears to be kosher.
