> 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.
