FAQ
Hi,

Why do I get this when I added a ZK node?

server (zk-107170197246-sf-development-cloudera): Mismatched CDH versions:
host has NONE but role expects 4.

Also..I have three ZK servers. So.....per the below..... why are the ZK
servers not talking? I thought that when I add servers....cloudera would
automatically have the right services talking.....

What do I need to do to resolve?

zookeeper: Service zookeeper has 1 Server. Cloudera suggests at least 3
Servers for ZooKeeper.
zookeeper2: Service zookeeper2 has 1 Server. Cloudera suggests at least 3
Servers for ZooKeeper.
zookeeper3: Service zookeeper3 has 1 Server. Cloudera suggests at least 3
Servers for ZooKeeper.

Thanks

    Hi,


    Cloudera..was there an issue with the question?

    See the attached what I am seeing. I was under the impression that
    couldera manager will have services talking.

    Doing a manually install if ZK across three nodes is easy peasy for other
    apps I am using.

    So....cloudera..how do I add ZK nodes that cluster?

    Thanks

    You need three instances within a single ZK service, not three ZK
    services. Delete zookeeper2 and zookeeper3, and head back to zookeeper
    and do the below:

    CM -> zookeeper -> Instances -> Add -> Add two additional ZK hosts in
    the interface presented. Restart zookeeper.
