>  // Allocation key is used by both of scheduler and RM to track allocations.
>  // It doesn't have to be same as RM's internal allocation id (such as Pod name of K8s or ContainerID of YARN).
>  // Allocations from the same AllocationAsk which are returned to the RM at the same time will have the same allocationKey.
>  // The request is considered an update of the existing AllocationAsk if an ALlocationAsk with the same allocationKey 
>  // already exists.

>  // Priority of ask
>  Priority priority = 6;

>  // A set of tags for this spscific AllocationAsk. Allocation level tags are used in placing this specific
>  // ask on nodes in the cluster. These tags are used in the PlacementConstraints.
>  // These tags are optional.
>  map<string, string> tags = 8;
>  // The name of the TaskGroup this ask belongs to
>  string taskGroupName = 9;
>  // Is this a placeholder ask (true) or a real ask (false), defaults to false
>  // ignored if the taskGroupName is not set
>  bool placeholder = 10;
> }
> {code}
> yunikorn.apache.org/ignoreUnschedulableNodes: true
> default value is false.
> For every daemonset pod, set this tag with the value true. So the core side can pick up to ignore the unschedulable nodes and continue to schedule onto them.
