Unable to Access kerberized cluster from my mac machine. Getting 401 Authentication error in curl

[#1]

try -k i.e, curl -i -k -u

[#2]

Can you verify the NN is listening on the public interface? Since you're able to ssh using the public hostname, but attempts to use WebHDFS don't show up in the NN log, it sounds like NN might only be listening on the internal interface.

* gss_init_sec_context() failed: : unknown mech-code 0 for mech unknown
