Kevin Bates created TOREE-437:
---------------------------------
Summary: 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
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.
