> Improve AvailableSpaceRackFaultTolerantBlockPlacementPolicy logic

> Key: HDFS-17247
> URL: https://issues.apache.org/jira/browse/HDFS-17247
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: Haiyang Hu
> Assignee: Haiyang Hu
> Priority: Major
> Labels: pull-request-available

> * The AvailableSpaceBlockPlacementPolicy has made some optimizations such as
> HDFS-14578 can have local node optimization and HDFS-17210 can avoid choosing
> nodes with higher storage,
> 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.
> * Improve some doc descriptions and configuration parameters.
