What Should I Do If the ZooKeeper Component Is Unavailable When I Buy an MRS Cluster?

Question:

Why Cannot I Find the ZooKeeper Component When I Buy an MRS Cluster?

Answer:

  • 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.

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

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