-------------------------------------------

             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)}}.
