--------------------------------------
Summary: Log additional information on preemption
Key: YUNIKORN-2052
URL: https://issues.apache.org/jira/browse/YUNIKORN-2052
Project: Apache YuniKorn
Issue Type: Improvement
Components: core - scheduler
Reporter: Craig Condit
Currently, when we preempt tasks, we log some information about the victim:
{code:java}
// SOURCE: pkg/scheduler/objects/preemption.go
log.Log(log.SchedPreemption).Info("Preempting task",
zap.String("applicationID", victim.GetApplicationID()),
zap.String("allocationKey", victim.GetAllocationKey()),
zap.String("nodeID", victim.GetNodeID()),
zap.Stringer("resources", victim.GetAllocatedResource()))
{code}
We should log some additional information to make it easier to correlate the
preemption with the ask that triggered it:
- applicationID of ask => "askApplicationID"
- allocationKey of ask => "askAllocationKey"
- queue of ask => "askQueue"
- queue of victim => "victimQueue"
For clarity we should also rename a few of the existing output items:
- "applicationID" => "victimApplicationID"
- "allocationKey" => "victimAllocationKey"
