Jing Zhao updated HDFS-7743:
----------------------------
Description: 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. (was: In

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}}.)
