[GitHub] alex-the-man commented on issue #48: [LIVY-41] Let users access sessions by session name

   Have we considered the potential impact of this change for Livy multi-master HA?
   To support multi-master HA without this feature, the only thing we need is a distributed atomic counter (which ZK offers).
   With this change, we have to enforce session names are unique across multiple masters. This makes multi-master HA more complicated.
