Copying the backed up data to the CDP cluster

You can copy your backed up data to the target CDP cluster in two ways: using distcp or using the Replication Manager.

Using distcp to copy the backed up data

Use the following command to copy your backed up Kudu data to the target CDP cluster:

sudo -u hdfs hadoop distcp hdfs:///kudu/kudu-backups/* hdfs://cluster-2.cluster_name.root.hwx.site/kudu/kudu-backups/

Using Replication Manager to copy the backed up data

HDFS replication enables you to copy (replicate) your HDFS data from one HDFS service to another, synchronizing the data set on the destination service with the data set on the source service, based on a specified replication policy.

For more information, see HDFS replicaton policy.
