Lei (Eddy) Xu commented on HDFS-10636: -------------------------------------- Hi, [~virajith] Thanks for working on this. A few questions. * In {{FsDatasetImpl#fetchReplication}} , please remove the usage {{LOG.info}}. * In {{ReplicaInfo.java}}. The following comments seem irrelevant to the code below. {code} /** directory where block & meta files belong. */ {code} Also please do not remove the comments for the constroctors. * {{breakHardlinksIfNeeded}}, {{ copyMetadata}} and {{copyBlockdata}} should not be in {{ReplicaInfo}}. Or should not use {{File}} as input. * {{ReplicaUnderRecovery}}. Is there a way to avoid casting {{ReplicaInfo}} to {{LocalReplica}}? * In general, there are places in this patch that return {{ReplicaInfo}} for {{FinalizedReplica}}. which would makes type system weaker and is not future-proof. Is it necessary to be changed?
