Todd Lipcon commented on HADOOP-7119:
-------------------------------------

bq. (In the case of the existent Kerberos code in Hadoop, I know it was reviewed by the paranoids at Y!.)

I think it's important that both outside "security experts" and also "framework experts" review code -- for example, when I reviewed the security work last summer I found several root exploits and data confidentiality exploits that the Y paranoids missed in their review.

Security is never perfect. The more eyes the better. Who those eyes happen to be is probably less important so long as they're not malicious.

> 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.
