Luke Lu commented on HADOOP-9421:
---------------------------------
bq. Luke's patch is 8-11ms slower with Kerberos than mine
Ah, that's probably due to my unoptimized patch does initial token twice (one
in INITIATE and the other in REINITIATE), which causes an extra round trip to
KDC to get service ticket. But I can fix this with no protocol changes and
eliminate the difference. OTOH, I can further eliminate the NEGOTIATE round
trip for Kerberos in normal/stead state cases.
