Uses of BlockLocationPolicy in alluxio.client.block.policy

Classes in alluxio.client.block.policy that implement BlockLocationPolicy

Modifier and Type	Class and Description
class	CapacityBasedDeterministicHashPolicy A policy that pseudo-randomly distributes blocks between workers according to their capacity, so that the probability a worker is chosen is equal to the ratio of its capacity over total capacity of all workers, provided that the blocks requested follow a uniform distribution.
class	CapacityBaseRandomPolicy Randomly distribute workload based on the worker capacities so bigger workers get more requests.
class	DeterministicHashPolicy This policy maps the blockId to several deterministic Alluxio workers.
class	LocalFirstAvoidEvictionPolicy A policy that returns the local worker first, and if the local worker doesn't exist or doesn't have enough availability, will select the nearest worker from the active workers list with sufficient availability.
class	LocalFirstPolicy A policy that returns the local worker first, and if the local worker doesn't exist or doesn't have enough capacity, will select the nearest worker from the active workers list with sufficient capacity.
class	MostAvailableFirstPolicy A policy that returns the worker with the most available bytes.
class	RoundRobinPolicy A policy that chooses the worker for the next block in a round-robin manner and skips workers that do not have enough space.
class	SpecificHostPolicy Always returns a worker with the hostname specified by PropertyKey.WORKER_HOSTNAME (alluxio.worker.hostname).
