> pointed out that {{LeafQueue#pendingOrderingPolicy}} should NOT be assumed
> to be same as active applications ordering policy. It causes an issue when
> using fair ordering policy.
> Expectations of this JIRA should include
> # Create FifoOrderingPolicyForPendingApps which extends FifoOrderingPolicy.
> # Comparator of new ordering policy should use
> RecoveryComparator,PriorityComparator and Fifocomparator in order
> respectively.
> # Clean up {{LeafQueue#pendingOPForRecoveredApps}} which is no more required
> once new fixed ordering policy is created pending applications.
