----------------------------------
Summary: Add ability to an agent to cancel queued/running tasks
Key: AMBARI-6768
URL: https://issues.apache.org/jira/browse/AMBARI-6768
Project: Ambari
Issue Type: Task
Components: agent
Affects Versions: 1.7.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Fix For: 1.7.0
Agent should accept a list of CANCEL_COMMANDs inside heartbeat response
(cancelCommands). CANCEL_COMMAND looks like:
{
target_task_id: "4-3"
reason: "Aborted by a user via API" // Text that has been provided at
abort_reason field via API
}
For cancelled tasks (that were in pending or in_progress state), a command
report should be generated and sent to a server.
As of now, only cancelling ordinary commands should be supported.
