[~yuanbo], here is what happened in your case.
1. hostname {{localhost}} is mapped to principal {{HTTP/localhost}} during
KerberosAuthenticationHandler.java:init.
{code}
2016-12-14 15:48:34,459 TRACE server.KerberosAuthenticationHandler
(KerberosAuthenticationHandler.java:init(279)) - Map server: localhost to
principal: HTTP/localhost
{code}
2. authenticate request comes in
{code}
2016-12-14 15:48:34,482 TRACE server.KerberosAuthenticationHandler
(KerberosAuthenticationHandler.java:authenticate(400)) - SPNEGO starting for
url: http://localhost:39910/foo/bar
{code}
3. The localhost to principal lookup somehow failed with an empty principal as
shown below, which failed the test.
{code}
2016-12-14 15:48:34,495 TRACE server.KerberosAuthenticationHandler
(KerberosAuthenticationHandler.java:run(421)) - SPNEGO with principals: []
{code}
The only difference is in all the pass cases the HashMap lookup successfully
find the right principal. I can't see obvious reason why the single principle
is not being added into the HashMap during init(). I attach a new patch with
additional tracing. [~yuanbo], can you try it out and post the result?

> principle used in these test are incomplete: HTTP/localhost assuming the
