Field Reference
-
TaskStates-TaskStatesis a map of tasks to their current state and the latest events that have effected the state.A task can be in the following states:
TaskStatePending- The task is waiting to be run, either for the first time or due to a restart.TaskStateRunning- The task is currently running.TaskStateDead- The task is dead and will not run again.
The latest 10 events are stored per task. Each event is timestamped (unix nano-seconds) and has one of the following types:
Driver Failure- The task could not be started due to a failure in the driver.Started- The task was started; either for the first time or due to a restart.Terminated- The task was started and exited.Killed- The task was killed by an user.Received- The task has been pulled by the client at the given timestamp.Failed Validation- The task was invalid and as such it didn't run.Restarting- The task terminated and is being restarted.Not Restarting- the task has failed and is not being restarted because it has exceeded its restart policy.Downloading Artifacts- The task is downloading the artifact(s) specified in the task.Failed Artifact Download- Artifact(s) specified in the task failed to download.
Depending on the type the event will have applicable annotations.
