> Key: HADOOP-15887
> URL: https://issues.apache.org/jira/browse/HADOOP-15887
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools/distcp
> Affects Versions: 2.8.2, 3.0.0
> Reporter: Tao Jie
> Assignee: Tao Jie
> Priority: Major

>
> 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.
