Sanjay Radia commented on HADOOP-9421:
--------------------------------------
bq. Client today does send/(send/read)+, and now it's send/read/(send/read)+.
Daryn, I assume the first read in the new version is to read the server's list
of auth methods.
Generally the preferred approach is: client sends preferred auth with a list of
alternatives client can do and server either accepts it or throws back a
counter with one of the alternates that the client proposed. This would avoid
an extra trip in the normal case.
