Running the DistCp job on the HDP cluster

After you enable the "hdfs" user to run YARN jobs on the HDP cluster and make the required configuration changes on the Cloudera Private Cloud Base cluster, you can run the DistCp job to migrate the HDFS data from the secure HDP cluster to the unsecure Cloudera Private Cloud Base cluster.

  1. Make sure that you restart the cluster services before you run the DistCp job in the HDP cluster.
  2. Run the following hadoop distcp command: 
    hadoop distcp -D ipc.client.fallback-to-simple-auth-allowed=true [***SOURCE CLUSTER***]
 [***DESTINATION CLUSTER***]

    For example,

     hadoop distcp -D ipc.client.fallback-to-simple-auth-allowed=true
        hdfs://172.27.28.200:8020/tmp/test/hosts1 
    hdfs://172.27.110.198:8020/tmp/hosts1
