Venkat Ranganathan commented on HADOOP-10710:
---------------------------------------------

Just as an additional data point, HADOOP-10379  also breaks the use of OOZIE web console in
 secure clusters

> It seems that HADOOP-10379 introduced a bug on how hadoop.auth cookies are being constructed.
> Before HADOOP-10379, cookies were constructed using Servlet's {{Cookie}} class and corresponding
{{HttpServletResponse}} methods. This was taking care of setting attributes like 'Version=1'
and double-quoting the cookie value if necessary.
> HADOOP-10379 changed the Cookie creation to use a {{StringBuillder}} and setting values
and attributes by hand. This is not taking care of setting required attributes like Version
and escaping the cookie value.
> While this is not breaking HadoopAuth {{AuthenticatedURL}} access, it is breaking access
done using {{HtttpClient}}. I.e. Solr uses HttpClient and its access is broken since this
change.
> It seems that HADOOP-10379 main objective was to set the 'secure' attribute. Note this
can be done using the {{Cookie}} API.
> We should revert the cookie creation logic to use the {{Cookie}} API and take care of
the security flag via {{setSecure(boolean)}}.
