Subject Re: Local and remote metastores
Date Thu, 25 Aug 2011 00:48:48 GMT
Are there features that are only provided by the remote datastore
(like authorization)?

No. All features should be provided by both. In the case of
authorization, the problem is that it did not get fully tested with a
remote metastore. So you saw some small bugs when running
authorization on a remote metastore.

Thanks
