> ---------------------------------------
>
> Key: LENS-190
> URL: https://issues.apache.org/jira/browse/LENS-190
> Project: Apache Lens
> Issue Type: Bug
> Reporter: Arshad Matin
> Assignee: Himanshu Gahlaut
> Fix For: 2.0
>
>
> If some session is open and some resources have been added to that session.
> If we remove that resource and try to stop lens server(with session still
> open) then it will not be able to persist the session and this will create
> problem in restarting the lens server as server will try to open the
> persisted session.
