             Summary: Discover daemonset pods and tag with ignoreUnschedulableNodes attributes
                 Key: YUNIKORN-757
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-757
             Project: Apache YuniKorn
          Issue Type: Sub-task
            Reporter: Weiwei Yang


Define a tag for allocationAsk

{code}

message AllocationAsk {
 // 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.
 string allocationKey = 1;
 // The application ID this allocation ask belongs to
 string applicationID = 2;
 // The partition the application belongs to
 string partitionName = 3;
 // The amount of resources per ask
 Resource resourceAsk = 4;
 // Maximum number of allocations
 int32 maxAllocations = 5;
 // Priority of ask
 Priority priority = 6;
 // Execution timeout: How long this allocation will be terminated (by scheduler)
 // once allocated by scheduler, 0 or negative value means never expire.
 int64 executionTimeoutMilliSeconds = 7;
 // 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.
