    Description
    CentralizedOpportunisticContainerAllocator
    The CentralizedOpportunisticContainerAllocator allocates opportunistic containers by considering all the nodes present in the cluster, after modifying the container sizes to respect the limits set by the ResourceManager.
    ClusterNode
    Represents a node in the cluster from the NodeQueueLoadMonitor's perspective
    ClusterNode.Properties
    Properties class used to initialize/change fields in ClusterNode.
    NodeQueueLoadMonitor
    The NodeQueueLoadMonitor keeps track of load metrics (such as queue length and total wait time) associated with Container Queues on the Node Manager.
    NodeQueueLoadMonitor.LoadComparator
    The comparator used to specify the metric against which the load of two Nodes are compared.
    QueueLimitCalculator
    This class interacts with the NodeQueueLoadMonitor to keep track of the mean and standard deviation of the configured metrics (queue length or queue wait time) used to characterize the queue load of a specific node.
