FAQ
Hi,

Today, I tried to install a brand new latest CDH (free version) cluster of
3 nodes from scratch in AWS EC2. I used automatic method using CM.
Everything OK until the inspection part. I have the following errors:
I ran the same installation last week, it was fine. Anything I missed?

    Hi Cloudera,
    I do think something wrong (a bug) with the CM installer on EC2 automatic
    version. Can you please try it?
    There are not many choices I can have for the automatic version on EC2 & I
    setup a cluster every Monday successfully until yesterday.

    Please help,

    Hi Aaron,

    Did the installation succeed on host ip-10-72-138-63.ec2.internal? Seems
    like the CDH packages did not get installed on it. Did you try rerunning
    the host inspector?

    Try going to the that host and see if CDH packages are installed (command
    depends on OS, if you're on RHEL run "yum list | grep hadoop").

    Also, can you please attach the agent logs for that host?

    Thanks.

    Hi Omar,

    Thanks for the reply. I am running Ubunto 12.04 on EC2.

    Yes. The auto installation (step #7 ) seems fine. The errors appeared on
    Host inspector (step #8), as I copy/paste the message in the first post.

    I think I knew what happened in the newest version of the installer.
    In the previous version of CM auto CDH installer, the manager host where
    runs CM manager was not a part of the CDH Clouster, so it did not have hdfs
    & the inspector did not check it during the CDH installation process.
    Now, the newest version installer checks CDH(hdfs etc) on the host where
    runs CM, which is wrong I think.

    Please help and correct me, if I am wrong.

    Thanks again,

    Aaron A

    Hi Omar,

    Thanks for the reply. I am running Ubunto 12.04 on EC2.

    Yes. The auto installation (step #7 ) seems fine. The errors appeared on
    Host inspector (step #8), as I copy/paste the message in the first post.

    I think I knew what happened in the newest version of the installer.
    In the previous version of CM auto CDH installer, the manager host where
    runs CM manager was not a part of the CDH Clouster, so it did not have hdfs
    & the inspector did not check it during the CDH installation process.
    Now, the newest version installer checks CDH(hdfs etc) on the host where
    runs CM, which is wrong I think.

    Please help and correct me, if I am wrong.

    Thanks again,

    Aaron A

    Did the installation succeed on host ip-10-72-138-63.ec2.internal? Seems
    like the CDH packages did not get installed on it. Did you try rerunning
    the host inspector?

    Try going to the that host and see if CDH packages are installed (command
    depends on OS, if you're on RHEL run "yum list | grep hadoop").

    Also, can you please attach the agent logs for that host?

    Thanks.

    Hi Aaron,

    To help me understand better, when you started the wizard, did you
    configure it to create 3 or 4 instances? Also, you're saying the 4th host
    that's showing up with no CDH info in the host inspector is actually the
    host that CM is running on?

    The wizard should not be installing the agent on the CM host, did you
    install the agent packages manually on the CM host?

    If you don't want to be using that host in your cluster then you would have
    to SSH into that host and run: sudo service cloudera-scm-agent stop

    Hi Omar,

    -- Your comments: "did you configure it to create 3 or 4 instances?"
    -- My answer: I tried to create a cluster of 3 instances on EC2. CM was
    running on a different same version Ubuntu host.

    -- Your comments: "Also, you're saying the 4th host that's showing up with
    no CDH info in the host inspector is actually the host that CM is running
    on?"
    -- My answer: Yes. The wizard complains "No CDH info" on the CM host, which
    is not a part of the cluster.

    -- Your comments: "The wizard should not be installing the agent on the CM
    host, did you install the agent packages manually on the CM host?"
    -- My answer: I agree with you and I did install agent packages on the CM
    host manually, because of CM upgrade. According to
    http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Free/latest/Cloudera-Manager-Free-Edition-Installation-Guide/cmfeig_topic_9_4.html,
    I did:

    sudo apt-get install cloudera-manager-server cloudera-manager-agent cloudera-manager-daemons


    -- Your comments: "If you don't want to be using that host in your cluster
    then you would have to SSH into that host and run: sudo service
    cloudera-scm-agent stop"
    -- My comments: It worked after doing this.

    Thanks very much for the help and I am all set now.

    Hi Aaron,

    To help me understand better, when you started the wizard, did you
    configure it to create 3 or 4 instances? Also, you're saying the 4th host
    that's showing up with no CDH info in the host inspector is actually the
    host that CM is running on?

    The wizard should not be installing the agent on the CM host, did you
    install the agent packages manually on the CM host?

    If you don't want to be using that host in your cluster then you would
    have to SSH into that host and run: sudo service cloudera-scm-agent stop

    Hi Omar,

    Thanks for the reply. I am running Ubunto 12.04 on EC2.

    Yes. The auto installation (step #7 ) seems fine. The errors appeared on
    Host inspector (step #8), as I copy/paste the message in the first post.

    I think I knew what happened in the newest version of the installer.
    In the previous version of CM auto CDH installer, the manager host where
    runs CM manager was not a part of the CDH Clouster, so it did not have hdfs
    & the inspector did not check it during the CDH installation process.
    Now, the newest version installer checks CDH(hdfs etc) on the host where
    runs CM, which is wrong I think.

    Please help and correct me, if I am wrong.

    Thanks again,

    Aaron A

    Hi Aaron,

    Did the installation succeed on host ip-10-72-138-63.ec2.internal?
    Seems like the CDH packages did not get installed on it. Did you try
    rerunning the host inspector?

    Try going to the that host and see if CDH packages are installed
    (command depends on OS, if you're on RHEL run "yum list | grep hadoop").

    Also, can you please attach the agent logs for that host?

    Thanks.

    Hi Cloudera,
    I do think something wrong (a bug) with the CM installer on EC2
    automatic version. Can you please try it?
    There are not many choices I can have for the automatic version on EC2
    & I setup a cluster every Monday successfully until yesterday.

    Please help,
