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 | > https://issues.apache.org/jira/browse/HDFS-7369?focusedCommentId=14361131&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14361131] > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
