    Hi all:

    I found the HMC was often unstable to uninstall clusters or deploy clusters successfully.
    I tried to unstall cluster , then deploy cluster many times , again and agin , and at last, it’s ok without any
    reason,However, I did not think it make sense. Does any one could explain this phenomenon for me ?
    Did any one suffer this as me ? What’s the correct procedure to re-deploy clusters?
    Is the following proceduce correct that “Uninstall clusters firstly, then add nodes to deploy clusters?”
    My HDP environment :1 Name Node(with HMC) +3 Data nodes ,CentOS 6.3.

    Thanks in advance.

    Regards,
    Jeff

    Jeff,

    If by ‘re-deploy’ you mean add a node to your cluster, then no, this is not the correct procedure. To add nodes to your cluster you create a text file with all of the FDQN’s of the new nodes, and then use the “add nodes” tab in HMC.
