Why Is the ZooKeeper Component Unavailable When an MRS Cluster Is Created?¶

If you create a cluster of a version earlier than MRS 3.x, ZooKeeper is installed by default and is not displayed on the GUI.

If you create a cluster of MRS 3.x or later, ZooKeeper is available on the GUI and is selected by default.

After the cluster is created, the ZooKeeper component is available on the Components page.
