Alejandro Abdelnur created HADOOP-10710:
-------------------------------------------
Summary: hadoop.auth cookie is not properly constructed according
to RFC2109
Key: HADOOP-10710
URL: https://issues.apache.org/jira/browse/HADOOP-10710
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.4.0
Reporter: Alejandro Abdelnur
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)}}.
