Haiyang Hu updated HDFS-17247: ------------------------------ Description: The AvailableSpaceBlockPlacementPolicy has made some optimizations such as HDFS-14578,HDFS-17210, the AvailableSpaceRackFaultTolerantBlockPlacementPolicy need keep same logics of optimization same as ASBPP. Currently considering implementing a public class, such as AvailableSpaceBlockPlacementPolicyUtils, and abstract some public methods such as {code:java} chooseLocalStorage, swapStorageTypes, select, compareDataNode {code} the AvailableSpaceBlockPlacementPolicy and AvailableSpaceRackFaultTolerantBlockPlacementPolicy can call related methods in AvailableSpaceBlockPlacementPolicyUtils. If there are related optimizations later, they can be modified based on AvailableSpaceBlockPlacementPolicyUtils. was: The AvailableSpaceBlockPlacementPolicy has made some optimizations such as HDFS-14578,HDFS-17210, the AvailableSpaceRackFaultTolerantBlockPlacementPolicy need keep same logics of optimization same as ASBPP.
