--------------------------------
Summary: Provide a slider command to kill all stranded containers
continuing to run post stop command
Key: SLIDER-479
URL: https://issues.apache.org/jira/browse/SLIDER-479
Project: Slider
Issue Type: Bug
Reporter: Gour Saha
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.
