Peter Bacsko created YUNIKORN-2683:
--------------------------------------
Summary: Unnecessary error is logged when resource usage is
increased
Key: YUNIKORN-2683
URL: https://issues.apache.org/jira/browse/YUNIKORN-2683
Project: Apache YuniKorn
Issue Type: Bug
Components: core - scheduler
Reporter: Peter Bacsko
The refactored code in YUNIKORN-2542 contains an unnecessary warning message:
{noformat}
appGroup := userTracker.getGroupForApp(applicationID)
log.Log(log.SchedUGM).Debug("Increasing resource usage for user",
zap.String("user", user.User),
zap.String("queue path", queuePath),
zap.String("application", applicationID),
zap.String("group", appGroup),
zap.Stringer("resource", usage))
groupTracker := m.GetGroupTracker(appGroup)
if groupTracker == nil {
log.Log(log.SchedUGM).Error("group tracker should be available
in groupTrackers map",
zap.String("application", applicationID),
zap.String("group", appGroup))
return
}
...
{noformat}
We don't always have a {{groupTracker}}. The previous code simply called
{{increaseTrackedResource()}} on an empty tracker:
{noformat}
func (ut *UserTracker) increaseTrackedResource(queuePath string, applicationID
string, usage *resources.Resource) {
ut.Lock()
defer ut.Unlock()
ut.events.sendIncResourceUsageForUser(ut.userName, queuePath, usage)
hierarchy := strings.Split(queuePath, configs.DOT)
ut.queueTracker.increaseTrackedResource(hierarchy, applicationID, user,
usage)
gt := ut.appGroupTrackers[applicationID]
log.Log(log.SchedUGM).Debug("Increasing resource usage for group",
zap.String("group", gt.getName()),
zap.Strings("queue path", hierarchy),
zap.String("application", applicationID),
zap.Stringer("resource", usage))
gt.increaseTrackedResource(queuePath, applicationID, usage,
ut.userName) <- can be null
}
{noformat}
