bq. +1 for branch-1.2
Thanks, Sean. I pushed this.
> Incorrect ZK ACL set for HBase superuser
> ----------------------------------------

> Project: HBase

> Shreya was doing some testing of a deploy of HBase, verifying that the ZK
> ACLs were actually set as we expect (yay, security).
> She noticed that, in some cases, we were seeing multiple ACLs for the same
> user.

> 'sasl,'hbase
> : cdrwa
> {noformat}
> After digging into this (and some insight from the mighty [~enis]), we
> realized that this was happening because of an overridden value for
> {{hbase.superuser}}. However, the ACL value doesn't match what we'd expect to
> see (as hbase.superuser was set to {{cstm-hbase}}).
> After digging into this code, it seems like the {{auth}} ACL scheme in
> ZooKeeper does not work as we expect.
> {code}
> if (superUser != null) {
> acls.add(new ACL(Perms.ALL, new Id("auth", superUser)));
> }
> {code}
> In the above, the {{"auth"}} scheme ignores any provided "subject" in the
> {{Id}} object. It *only* considers the authentication of the current
> connection. As such, our usage of this never actually sets the ACL for the
> superuser correctly.
