Because the default placement policy chooses the local node to > store the first replication. > In https://issues.apache.org/jira/browse/HDFS-3702 we add a flag in DFSClient > to avoid replicating to the local datanode. We can make use of this flag in > Distcp. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
