Vinayakumar B commented on HDFS-9542:
-------------------------------------

bq. Just wonder if it's a good idea to rename: generationStampV1 => 
legacyGenerationStamp; generationStampV2 => generationStamp, similar for other 
variables, as we have legacy block and block.
Good to see this.

+1 for the current refactor anyway. thanks [~jingzhao].

> Semantically BlockIdManager should be a field in BlockManager instead of 
> FSNamesystem.
