Preparing to create Hive ACID table replication policies
Before you create a Hive ACID table replication policy, you must prepare the clusters
for replication.
To perform Hive ACID table replication using Replication Manager, Cloudera
Manager Server must manage the target cluster. You can use the same server or a peer
Cloudera Manager Server to manage the source cluster. Hive ACID table replication
policies use Hive scheduler to schedule the frequency of replication policy job
runs.

Configure a peer relationship only if the source cluster is managed
by a different Cloudera Manager server than the target
cluster. For more information, see Configuring a peer relationship.
Ensure that the hive user and the hive group
have 0755 port permission to the staging location if the
target cluster uses Dell EMC Isilon
storage.
Configure the hive.repl.cm.enabled=true key-value pair
on the source cluster for the following services to turn on the
ChangeManager:
Service
Action
Hive-on-Tez
For example,
Hive-on-Tez-1
On the Configuration tab, search
for Hive Service Advanced Configuration Snippet
(Safety Valve) for hive-site.xml property
and set the key-value pair
Hive
For example,
Hive-1
On the Configuration tab, search
for Hive Service Advanced Configuration Snippet
(Safety Valve) for hive-site.xml property
and set the key-value pair.
Hive
For example,
Hive-1
On the Configuration tab, search
for Enable ChangeManager for Hive
replication parameter and select it.
