Shrikant commented on LIVY-874:
-------------------------------
from the livy log:
21/11/18 12:05:56 INFO InteractiveSession: Cannot recover interactive session
29 because its RSCDriver URI is unknown.
It seems session associated with application in accepted state can not be
recovered, is it by design or a bug?
> App in Accepted state fails after Livy restart
