Subject [jira] Commented: (HIVE-842) Authentication Infrastructure for Hive
Date Fri, 22 Oct 2010 21:22:24 GMT


Todd Lipcon commented on HIVE-842:

Hey Pradeep. Those changes seem reasonable. I'm not personally a fan of the "login user" concept
in Hadoop security - it's static state, which prevents servers which may want to use multiple
principals from doing so easily (eg if running a hive server with an embedded metastore, you
may need a different principal for the two different pieces). But given that there is no "renewer"
thread for non-loginuser keytab logins, it may be the only choice for now.

> This issue deals with the authentication (user name,password) infrastructure. Not the
authorization components that specify what a user should be able to do.
