----------------------------------------------------------------
I'm wondering if at that point (where the exception is thrown) we can trust
that `Shiro` has validated the request, ie: authenticated the user if the url's
path was configured to use `authcBasic`. If so, I guess `ShiroProvider` can
continue processing the request instead of crashing.
I've tried this approach locally and it seems to work: I can navigate through
Hadoop UI anonymously and then when tried to load a secured path (eg:
`/jobhistory/conf/job_1555073080493_0014`) basic authentication is requested.
I'm attaching a patch with the changes: [^patch.patch]
