Subject [jira] [Commented] (HBASE-15780) Expose AuthUtil as IA.Public
Date Fri, 13 May 2016 23:26:12 GMT

Sean Busbey commented on HBASE-15780:

Looks good to me for 1.3. The only comment is that I would prefer to mark interfaces as public-evolving
to have a little bit more of a room if we need to, but that's a nit in fact.

I had considered making them IA.Evolving but 1) these things don't appear to change much thus
far and 2) this is something pretty critical to downstream applications, so changing it has
a high cost even if we say it's experimental.

Personally I think it would be a little cleaner if UGI handled this itself the same way it
does with refreshing tickets from the credential cache, but that's not something we can really
control. I have a patch up on HADOOP-9567 that adds a background thread for keytab based logins
but it doesn't look to be getting any traction.

Part of what I really like on this approach is that we hide UGI entirely from downstream users.
HBase users shouldn't have to care about Hadoop Authentication stuff, IMHO. although we are
still exposing hadoop.Configuration, that's historically been a much more straightforward
part of Hadoop.

> Make AuthUtils IA.Public so that we can point it out to folks who want to build long-lived
services that talk to secure HBase clusters without concerning them with Hadoop APIs like
UGI.
