The scm inspector fail inspite of the previous installation step is
indicated as successful.

my scm is running on a ubuntu 12.04.01 vm and i was attempting to configure
a host running ubuntu 12.04.1 clean install on a AWS vm.

The scm detected the host fine and the install step completed successfully.
Here <https://gist.github.com/4199800> is the logs from the installation
step. On the host machine the "cloudera-scm-agent" service seems to be
running. Also, oracle jdk and the various hadoop packages are installed.

The next step where the inspector runs I get a message "The inspector
failed to run on all hosts." and the host does not get added.

    I see that you're on EC2.

    Most likely the CM Server host is firewalled away from the agent hosts or
    the agent hosts are firewalled away from the server. We require
    communication to be allowed in both directions (port 7182 agent->server,
    port 9000 the other).

    Arun,
    To add to Philip's comment, in order to allow communication, you will have
    to update your security group on EC2.

    Hi,

    Even I am not able to see the hosts, after complete installation.

    The inspector says: The inspector failed to run on all hosts.

    I am running this with 3 VM Nodes, My firewall in all the 3 nodes is
    disabled.

    Regards
    Azzan

    Thanks guys. Was primarily a firewall problem.

    If you are using AWS, make sure that all your hosts and the cloudera
    manager machine are in the same security group.
    Then turn on ICMP and TCP/IP all ports within the security group.

    thanks
    Arun
