To kill an Application you can also use the Application State by using a PUT operation to set the application state to KILLED. For example:

curl -v -X PUT -d '{"state": "KILLED"}''http://localhost:8088/ws/v1/cluster/apps/application_1409421698529_0012'

Hope that helps

@Geoffrey Shelton OkotI am asking to kill the container directly. I am aware of killing application. Thank you.

@Geoffrey Shelton Okot we are writing a multi-node application that "heals" itself when a node is lost. In order to test the "healing" process we need to kill one of the node containers. Is there a way to do this? Is there any application in the Hadoop ecosystem that does this?

We are running our packages through slider in hadoop cluster as long running jobs.

@Ram D

Did you take a look at this.

https://slider.incubator.apache.org/docs/manpage.html

Commands for testing

These operations are here primarily for testing.

`kill-container <name> --id container-id`

Kill a YARN container belong to the application. This is useful primarily for testing the resilience to failures.

Container IDs can be determined from the application instance status JSON document.

use the slider kill-container command; it's how we test slider apps resilience to failure. There's also a built in chaos-monkey in slider; you can configure the AM to randomly kill containers (and/or its own). See Configuring the Chaos Monkey
