> In the work of erasure coding (HDFS-7285), we plan to extend the class BlockInfo to two subclasses: BlockReplicationInfo and BlockGroupInfo (HDFS-7716). To ease the HDFS-EC branch syncing with trunk, this jira plans to rename the current BlockInfo to BlockReplicationInfo in trunk.
> In the meanwhile, we can also use this chance to do some minor code cleanup. E.g., removing unnecessary overrided {{hashCode}} and {{equals}} methods since they are just the same with the super class {{Block}}.
