• Shows a row of information for each replication policy, and the following columns for each replication policy:

  • Internally generated ID for the replication policy. Click the column label to sort the replication policies.
  • Replication policy Name that you provide during replication policy creation.
  • Replication policy Type.
  • Source cluster in the replication policy.
  • Destination cluster in the replication policy.
  • Average Throughput per mapper/file for all the files written.
  • Replication job Progress.
  • Timestamp when the replication job Completed.
  • Replication policy job’s Next Run.

• Provides the following options under the Actions menu:

  • Show History opens the Replication History page for the replication policy.
  • Edit Configuration enables you to change the replication policy options.
  • Dry Run simulates a run of the replication job where no files or tables are copied. After the dry run completes, select Actions > Show History to view the potential error messages. The number and size of files or tables that are copied in an actual replication appears on the Replication History page.
  • Run Now initiates a replication job.
  • Collect Diagnostic Data opens the Send Diagnostic Data dialog box where you can:
    • Collect Diagnostic Data for the last 10 runs of the replication policy, and Download it as a ZIP file to your machine.
    • Select Send Diagnostic Data to Cloudera (optionally, add a Cloudera support ticket number and comments) and click Collect Diagnostic Data to automatically send the bundle to Cloudera Support for further assistance.
  • Disable an active replication policy. You can Enable it later, as necessary.

• Delete the replication policy permanently. Deleting a replication policy does not delete copied files or tables.
