RESPECT_PARTITION_EXCLUSIVITY

public static final SchedulingMode RESPECT_PARTITION_EXCLUSIVITY

When a node has partition (say partition=x), only application in the queue can access to partition=x AND requires for partition=x resource can get chance to allocate on the node.

When a node has no partition, only application requires non-partitioned resource can get chance to allocate on the node.

IGNORE_PARTITION_EXCLUSIVITY

public static final SchedulingMode IGNORE_PARTITION_EXCLUSIVITY

Only used when a node has partition AND the partition isn't an exclusive partition AND application requires non-partitioned resource.
