Hi Ranjith AFAIK Segmenting tables into databases won't help much as, again the Authorization issues would pop out. An user himself may be able to grant rights to access another db. Different metastores is an option, but again maintaining all of them is still a hassle, still you can do it. The fair solution is only on its way. :)

Is separate metastores and separate hive servers the only way to go here? Or can we segment tables into databases and then use hive authorization.
