> This is the list of internal servlets added by namenode.
> | Name | Auth | Need to be accessible by end users |
> | StartupProgressServlet | none | no |
> | GetDelegationTokenServlet | internal SPNEGO | yes |
> | RenewDelegationTokenServlet | internal SPNEGO | yes |
> |  CancelDelegationTokenServlet | internal SPNEGO | yes |
> |  FsckServlet | internal SPNEGO | yes |
> |  GetImageServlet | internal SPNEGO | no |
> |  ListPathsServlet | token in query | yes |
> |  FileDataServlet | token in query | yes |
> |  FileChecksumServlets | token in query | yes |
> | ContentSummaryServlet | token in query | yes |
> GetDelegationTokenServlet, RenewDelegationTokenServlet, CancelDelegationTokenServlet
and FsckServlet are accessed by end users, but hard-coded to use the internal SPNEGO filter.
> If a name node HTTP server binds to multiple external IP addresses, the internal SPNEGO
service principal name may not work with an address to which end users are connecting.  The
current SPNEGO implementation in Hadoop is limited to use a single service principal per filter.
> If the underlying hadoop kerberos authentication handler cannot easily be modified, we
can at least create a separate auth filter for the end-user facing servlets so that their
service principals can be independently configured. If not defined, it should fall back to
the current behavior.
