Aaron T. Myers commented on HADOOP-7119:
----------------------------------------
Sanjay, also note that some of tests which are part of the back-port require
Kerberos infrastructure to be present in order to run. Under the maven build
system, these tests will not be run by default, unless you provide the option
"-PtestKerberos" to mvn. We'll probably need to do something similar in ant for
the back-port.
> add Kerberos HTTP SPNEGO authentication support to Hadoop JT/NN/DN/TT

> Currently the JT/NN/DN/TT web-consoles don't support any form of
> authentication.
> Hadoop RPC API already supports Kerberos authentication.
> Kerberos enables single sign-on.
> Popular browsers (Firefox and Internet Explorer) have support for Kerberos
> HTTP SPNEGO.
> Adding support for Kerberos HTTP SPNEGO to Hadoop web consoles would provide
> a unified authentication mechanism and single sign-on for Hadoop web UI and
> Hadoop RPC.
