Thomas Graves commented on SPARK-21655:
---------------------------------------
The UI kill requests are acl protected. You do need to have auth for your UI
for that to work properly but I don't see any security issue there as you can
enforce it if you want to. Unless there was something else you were referring
to?
> Kill CLI for Yarn mode

> Similar to how standalone and Mesos have the capability to safely shut down
> the spark application, there should be a way to safely shut down spark on
> Yarn mode. This will ensure a clean shutdown and unregistration from yarn.
> This is the design doc:
