> ContainerAllocation.LOCALITY_SKIPPED is final static, and its .state should
> always be AllocationState.LOCALITY_SKIPPED. However, this variable is public
> and is accidentally changed to AllocationState.APP_SKIPPED in
> RegularContainerAllocator under certain conditions. Once that happens, all
> following LOCALITY_SKIPPED situations will be treated as APP_SKIPPED.
> Similar risks exist for
> ContainerAllocation.PRIORITY_SKIPPED/APP_SKIPPED/QUEUE_SKIPPED.
> ContainerAllocation.state should be private and should not be changed. If
> changes are needed, a new ContainerAllocation should be created.
