Tao Jie updated HADOOP-15887: ----------------------------- Attachment: HADOOP-15887.001.patch > Add an option to avoid writing data locally in Distcp > ----------------------------------------------------- > > Key: HADOOP-15887 > URL: https://issues.apache.org/jira/browse/HADOOP-15887 > Project: Hadoop Common > Issue Type: Improvement > Affects Versions: 2.8.2, 3.0.0 > Reporter: Tao Jie > Assignee: Tao Jie > Priority: Major > Attachments: HADOOP-15887.001.patch > > > When copying large amount of data from one cluster to another via Distcp, and > the Distcp jobs run in the target cluster, the datanode local usage would be > imbalanced. 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 (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
