---------------------------------
Summary: Killing a job attempts to transition non-active tasks
Key: AURORA-83
URL: https://issues.apache.org/jira/browse/AURORA-83
Project: Aurora
Issue Type: Bug
Components: Client, Scheduler
Reporter: Bill Farner
Priority: Minor
The client exposes a {{kill}} subcommand to kill jobs, which currently applies
to cron and non-cron jobs. This is translated into a {{killTasks}} RPC, and
the scheduler internally inspects the query to determine if this is a request
to kill a whole job. Acting on this RPC for a job means that the scheduler
attempts to transition a slew of tasks to {{KILLING}} state. This is benign,
but inefficient and can result in lots of log noise.
In the short term, the scheduler should restrict non-cron job-scoped kills to
only active tasks. Longer-term, we should expose a more explicit way for the
client to ask for a cron job to be unscheduled.
