             Summary: Fix inconsistent lock behavior in application.go
                 Key: YUNIKORN-1164
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1164
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: core - scheduler
            Reporter: Craig Condit


The {{Application}} object in {{pkg/scheduler/objects/application.go}} has inconsistent locking in several places:
 * {{getPlaceholderAllocations() }}accesses the allocations map unlocked which might cause issues.

 * Usages of {{clearStateTimer()}} also should be checked.

 * {{HandleApplicationEvent()}} and {{OnStateChange()}} assume the lock is held. However, {{timeoutStateTimer()}} calls {{HandleApplicationEvent()}} with no lock held.

We should look for any other potential issues here as well.
