             Summary: nil pointer error in webservice.getApplicationJSON()
                 Key: YUNIKORN-952
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-952
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: core - scheduler
            Reporter: Peter Bacsko


The implementation of the new method {{getApplicationsDAO()}} is incorrect:

{noformat}
func getApplicationsDAO(lists map[string]*scheduler.PartitionContext) []*dao.ApplicationDAOInfo {
	result := make([]*dao.ApplicationDAOInfo, 0, 32)

	for _, partition := range lists {
		size := partition.GetTotalCompletedApplicationCount() + partition.GetTotalApplicationCount()
		appList := make([]*objects.Application, size)
		appList = append(appList, partition.GetApplications()...)
		appList = append(appList, partition.GetCompletedApplications()...)
....
{noformat}

The slice creation is incorrect - the initial length should be 0, and the capacity should be set to the "size":
{noformat}
appList := make([]*objects.Application, 0, size)
{noformat}

Right now appList will contail "nil" elements after creation.
