[jira] [Created] (HDFS-7743) Code cleanup of BlockInfo and rename BlockInfo to BlockReplicationInfo

Jing Zhao created HDFS-7743:
-------------------------------

             Summary: Code cleanup of BlockInfo and rename BlockInfo to BlockReplicationInfo
                 Key: HDFS-7743
                 URL: https://issues.apache.org/jira/browse/HDFS-7743
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
            Reporter: Jing Zhao
            Assignee: Jing Zhao
            Priority: Minor


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}}.
