> Many existing names should be revised to avoid confusion when blocks can be 
> both replicated and erasure coded. This JIRA aims to solicit opinions on 
> making those names more consistent and intuitive.
> # In current HDFS _block recovery_ refers to the process of finalizing the 
> last block of a file, triggered by _lease recovery_. It is different from the 
> intuitive meaning of _recovering a lost block_. To avoid confusion, I can 
> think of 2 options:
> #* Rename this process as _block finalization_ or _block completion_. I 
> prefer this option because this is literally not a recovery.
> #* If we want to keep existing terms unchanged we can name all EC recovery 
> and re-replication logics as _reconstruction_.  
> # As Kai [suggested |

>  under HDFS-7369, several replication-based names should be made more generic:
> #* {{UnderReplicatedBlocks}} and {{neededReplications}}. E.g. we can use 
> {{LowRedundancyBlocks}}/{{AtRiskBlocks}}, and 
> {{neededRecovery}}/{{neededReconstruction}}.
> #* {{PendingReplicationBlocks}}
> #* {{ReplicationMonitor}}
> I'm sure the above list is incomplete; discussions and comments are very 
> welcome.
