Field Reference
-
TaskStates- A map of tasks to their current state and the latest events that have effected the state.TaskStateobjects contain the following fields:-
State: The task's current state. It can have one of the following values:-
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.
-
-
StartedAt: The time the task was last started at. Can be updated through restarts. -
FinishedAt: The time the task was finished at. -
LastRestart: The last time the task was restarted. -
Restarts: The number of times the task has restarted. -
Events- An event contains metadata about the event. The latest 10 events are stored per task. Each event is timestamped (Unix nanoseconds) and has one of the following types:-
Setup Failure- The task could not be started because there was a failure setting up the task prior to it running. -
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. -
Killing- The task has been sent the kill signal. -
Killed- The task was killed by a 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. -
Restart Signaled- The task was singled to be restarted. -
Signaling- The task was is being sent a signal. -
Sibling Task Failed- A task in the same task group failed. -
Leader Task Dead- The group's leader task is dead. -
Driver- A message from the driver. -
Task Setup- Task setup messages. -
Building Task Directory- Task is building its file system.
Depending on the type the event will have applicable annotations.
