Enable high availability for Streams Replication Manager

Streams Replication Manager is capable of running in high availability mode. This can be enabled by deploying multiple instances of the driver and service role in a cluster.

Streams Replication Manager is capable of running in high availability mode. By enabling high availability mode for Streams Replication Manager, you can ensure that the replication of data and the monitoring of replication continues even in the case of host failure. To enable Streams Replication Manager high availability, you must deploy multiple instances of the driver and service roles on the hosts in a cluster.

In Cloudera Private Cloud Base this can be done when installing a new cluster, when adding Streams Replication Manager to an existing cluster, or when Streams Replication Manager is already deployed and running on a cluster.

Enable high availability for Streams Replication Manager during cluster installation

To enable high availability for Streams Replication Manager during cluster installation, follow the cluster installation instructions available in Cloudera Private Cloud Base Installation Guide . During Step 7: Set Up a Cluster Using the Wizard, when prompted to assign roles to hosts, assign multiple role instances of the Streams Replication Manager driver and service roles to your hosts.

Enable high availability when adding Streams Replication Manager to an existing cluster

To enable high availability when adding Streams Replication Manager to an existing cluster, follow the service installation instructions available in Add Streams Replication Manager to an existing cluster. When assigning role instances to hosts, assign multiple role instances of the Streams Replication Manager driver and service roles to your hosts.

Enable high availability for an already running instance of Streams Replication Manager

To enable high availability for an already running instance of Streams Replication Manager, you must add additional driver and service role instances to your hosts. For more information, see Adding a Role Instance in the Cloudera Manager documentation.
