FAQ
Two quick questions....

Can a single install of Cloudera Manager (Free Edition) control multiple
clusters at once or is it limited to one? I can't see any way of creating a
second cluster.

Is there a step by step guide of using Cloudera Manager for setting up
clusters in Amazon EC2? The nearest I can find is a page for CDH2!
I am particularly thinking of advice regarding things like public/private
key setups. For instance do I have to add a private key to *root* on all
nodes, and use that to control the cluster? Or do I use the key set up when
creating the instances? Also the Ubuntu images seem to use user 'ubuntu'
instead of 'root' and I can't seem to specify that user instead of root.

Thanks

    Hi Alex,

    Multi-cluster support is only available in the Enterprise Edition.
    Please see this page for a list of the features included in each
    version:

    It just so happens that one of our users wrote this up today on his blog:

    You can specify which user to SSH as in the wizard screen. I've included a
    screenshot below. You should be able to use the same ssh key as you're
    using to connect to the instances.
