twmarshall opened a new pull request #161: KNOX-2026: Accept Impala's 
authentication cookies
URL: https://github.com/apache/knox/pull/161
 
 
   This patch modifies HadoopAuthCookieStore to accept cookies with
   Impala's cookie name, "impala.auth".
   
   It also updates a check that is used to ensure the cookie belongs to
   Knox - previously, this check parsed the cookie according to the
   specific format that Hadoop uses for its cookies and ensures that the
   Knox principal appears in the expected location.
   
   Impala uses a similar cookie format, but with a few changes such as
   fields being in a different order. The check is made more permissive
   such that it will accept any cookie that contains the Knox principal
   anywhere in it.
   
   Testing:
   - Deployed in a cluster and verified that Knox accepts and returns
     Impala's cookies as expected.
