It often happens that we see the NN schedule > replication on the last block of files very quickly after they're completed, > before the other DNs in the pipeline have a chance to report the new block. > This results in a lot of extra replication work on the cluster, as we > replicate the block and then end up with multiple excess replicas which are > very quickly deleted. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
