> For the owner of snapshots(not global admin user), currently list_snapshots returns empty if i just use simple acls for authorization but not use authentication.
> The code in AccessController.preListSnapshot:
> {code:java}
> if (SnapshotDescriptionUtils.isSnapshotOwner(snapshot, user)) {
> // list it, if user is the owner of snapshot
> AuthResult result = AuthResult.allow("listSnapshot " + snapshot.getName(),
> "Snapshot owner check allowed", user, null, null, null);
> accessChecker.logResult(result);
> }{code}
> And SnapshotManager.takeSnapshotInternal:
> {code:java}
> if (User.isHBaseSecurityEnabled(master.getConfiguration()) && user != null) {
>   builder.setOwner(user.getShortName());
> }
> {code}
> User.isHBaseSecurityEnabled：
> {code:java}
> public static boolean isHBaseSecurityEnabled(Configuration conf) {
>   return "kerberos".equalsIgnoreCase(conf.get(HBASE_SECURITY_CONF_KEY));
> }
> {code}
> So i think the logic of setOwner is used for authorization, not authentication, SnapshotManager should not only setOwner when hbase.security.authentication = kerberos, which cause listSnapshots returns empty when i just use simple acls.
