Replication of data from Google Cloud Storage to on-premise in HDFS

You must have a cluster registered with the Data Lifecycle Manager to which you want to replicate data from Google Cloud. The cluster must have enough storage to accept data that gets replicated. For more information, see Register cloud credentials.

You must create a new replication policy to replicate data from Google cloud storage to on-premise. You must have Infra Admin or DLM Admin role to perform this set of tasks.
  1. Select Policies and click Add Policy.
    By default, HDFS is selected as the service in the Create Replication Policy page.
  2. Enter the replication policy name and description.
  3. Click SELECT SOURCE.
  4. Select type as GCS and Cloud Credential from the drop-down and enter the path container_name/path for the GCS source.
  5. Click SELECT DESTINATION.

    You must have one or more clusters in the DLM application.

    If the target dataset is non-empty, a warning message appears Target dataset directory /xxxx/xxxis not empty. You can proceed by selecting the check-box supressWarnings. Opting to select the check-box overwrites the target location, considering the conflict resolution between HDFS location and Hive External Table base location directory.

  11. Click ADVANCED SETTINGS to set up the policy queue.
  12. Click CREATE POLICY.
    The data replication process is enabled.
