Attributes
heart_beat_timeout="seconds" (Initial value:60)
The time limit allowed for the heartbeat of another active Job Scheduler in a cluster to be delayed before the
Scheduler is declared dead.
When a Job Scheduler is inactive and operated with the -exclusive option set, then it may then become active.
Messages
[warn] SCHEDULER-836 Deactivating that dead Scheduler
[warn] SCHEDULER-996 No heart beat for seconds (time) - Scheduler seems to be dead
heart_beat_own_timeout="seconds" (Initial value:55)
This setting is used for self-regulation of a Job Scheduler. When a Job Scheduler notices that its own heartbeat
has been delayed longer than the time specified in this parameter, then it immediately stops and restarts itself. This
means that a Job Scheduler preempts being deactivated by another Scheduler and avoids the short-term
possibility of parallel operation because of a delayed heartbeat.
Messages
[ERROR] SCHEDULER-386 Last heart beat was time, seconds ago. Something is delaying Scheduler
execution, the Scheduler is aborted immediately
heart_beat_warn_timeout="seconds" (Initial value:10)
The time allowed for a delay in the heartbeat of a Job Scheduler before a warning is given out.
Messages
[warn] SCHEDULER-994 No heart beat for seconds (time), expecting heart beat within seconds
[warn] SCHEDULER-995 No heart beat for seconds (time), ignored for seconds because of recent
