View HDFS replication policy details
The Replications Policies page displays a row of information about each replication policy which includes recent messages about the last replication job run.
You can limit the replication jobs that are displayed by selecting filters on the left. If you do not see an expected policy, adjust or clear the filters. Use the search box to search the list of replication policies for path, database, or table names.

When a replication job is in progress, the Last Run column shows a spinner and progress bar, and each stage of the replication task is indicated in the message beneath the job's row. Click Command Details to view the command run details. If the job is successful, the number of files copied is indicated. If there have been no changes to a file at the source since the previous job, then that file is not copied. As a result, after the initial job, only a subset of the files may actually be copied, and this is indicated in the success message. Click to view more information about the completed job.
