Monitor a Replication Policy details on source CDH Cluster

[#1]

When a Hive replication policy executes in Replication Manager, the admin can monitor the details of the policy and its execution by checking the underlying command details on the source CDH Cluster's CM.

In order to export the data and metadata related to the specified Hive tables, multiple steps are executed in the source Cloudera Manager.

The Export Hive Metastore section has multiple steps that are explained below:

1. The first subcommand exports the Hive Metadata for the input database and tables.
2. The next step transfers the HDFS files from the CDH cluster to the cloud storage, which is used by the Data Lake cluster.
3. The next step exports the relevant Sentry permissions.

Once the above steps are executed successfully, the workflow resumes on the Data Lake cluster as explained in the previous section. 

With these steps, the administration now has a detailed behind-the-scenes view of the steps involved in running a Hive replication policy.
