Subject Re: user defined sessionId / URI for Livy sessions
Date Tue, 12 Sep 2017 02:05:16 GMT
I see. So based on this, we should manage a data structure in Livy Server
to keep all the live sessions' name. Also regarding to session recovery, we
should persist this structure to the reliable storage and recover after

I'm not pretty sure if it is a good feature or not. First because we
usually programmatically manage the session id, so from code level to
manager a session id or a session name there's no much difference; second,
usually it is hard for user to pick a unique name if one Livy Server has
many live sessions, by large chance the name will be conflicted, people
always like short, simple name.

Since I'm so familiar how people really use it, so it is just my two cents.
