> Cell interrupts do not occur in background
> ------------------------------------------
>
> Key: TOREE-437
> URL: https://issues.apache.org/jira/browse/TOREE-437
> Project: TOREE
> Issue Type: Improvement
> Components: Kernel
> Affects Versions: 0.2.0
> Reporter: Kevin Bates
> Assignee: Kevin Bates
> Labels: usability
>
> Whenever Toree is run in the background - either directly from the shell or
> indirectly from the Jupyter stack that is started in the background - cell
> interrupts (via ctrl-C or SIGINT from parent) are not received - resulting in
> the inability to interrupt long-running cells.
> This can be most simply demonstrated by invoking run.sh into the background
> (e.g., run.sh &) then issue ctrl-C (or `kill -2 <pid>`) to no avail.
> This is related to TOREE-33 but only pertains to cell interrupt functionality
> since complete life-cycle management is assumed by the parent for the
> shutdown (double ctrl-C) scenario.
