You can configure EDS to work with a ZooKeeper ensemble that uses a ZooKeeper observer. A ZooKeeper observer is a ZooKeeper node in an ensemble that does not participate in the leader election process in a high-availability environment.
For information about Apache ZooKeeper observers, see the ZooKeeper documentation in the following location:
To configure EDS to work with a ZooKeeper observer, perform the following tasks:
- Edit the configuration file of the ZooKeeper node that you choose as observer. Add the following configuration:
- Edit the configuration files of all ZooKeeper servers in the ensemble. Add
:observer to the server definition line of each observer.
- Edit the configuration files of the Administrator Daemon and the EDS Nodes in the deployment. Configure the
zkservers property to point to the ZooKeeper observer.
