Gour Saha commented on SLIDER-479:
----------------------------------
That makes sense, but it might be tricky to define "long period of time" since
for long running services (specifically for applications demanding a lot of
affinity) the agents are designed to continue to run and wait for the failed AM
to come back up. Definitely an application specific configurable time-period
can be exposed. Would ephemeral nodes in zk make sense to control the kill of
agents?

> Key: SLIDER-479
> URL: https://issues.apache.org/jira/browse/SLIDER-479
> Project: Slider
> Issue Type: Bug
> Reporter: Gour Saha
> Fix For: Slider 2.0.0
>
>
> A container can continue to run even after a slider stop command has been
> issued. One such scenarios is when NM of a non Slider-AM node is lost and
> before the Slider-AM could clean up the stranded agent (and the application
> processes) slider stop command was issued. In such a scenario even if the NM
> is brought back up it will not kill these containers.
> In a large cluster with several applications deployed/managed by slider there
> could easily be numerous such stranded containers.
> Slider client could expose a "stop-all" command or maybe an option "stop
> --clean" (or anything appropriate for this task) to do the cleanup. It can
> bring up the Slider-AM in clean mode (say) which will not start any
> application but will simply register to ZK and wait for agents to heart-beat
> into it. Each one of these agents will receive the terminate command from the
> AM and will do necessary cleanup and shutdown.
> This new command can be issued only after an application has been stopped.
> When invoked while the application is running this command should fail
> providing relevant information. This command can also provide a summary of
> how many stranded containers it cleaned up.
