FAQ
Hello Experts,

We have deployed cdh4.1.3 on our cluster using cloudera manager and will
be managing it using cdh going forward.

We were not using cloudera manager before and have developed certain
scripts to test cluster scalability and other features using shell
scripts. We use to start and stop hadoop services using service commands
through the scripts.

Now when using cloudera manager, shell commands for services will not work
as the services are managed by cm.

So it there a way I can use my command line scripts while still managing
the cluster using cloudera manager .

What is the recommended way to run bench marks on cluster managed by
cloudera manager.

Thanks,
Romit.

    Hi Romit,

    You should take a look at
    http://blog.cloudera.com/blog/2012/09/automating-your-cluster-with-cloudera-manager-api/
    for
    a walkthrough of CM's API support. You'll be able to use the python client
    (https://github.com/cloudera/cm_api) or just 'curl' to automate operations
    on the cluster.

    As for benchmarks, those tend to be MapReduce jobs, so you simply download
    the client configuration (or ask CM to deploy it to the relevant host
    you're running the benchmark from) and do that.

    Cheers,

    -- Philip

    Hi Romit,

    I suspect the scm-users@ list will be able to help you with this question.

    Romit,

    Your existing scripts likely won't work as is. However, Cloudera Manager
    does come with an extensive REST API that allows you to start/stop services
    and make configuration changes, among other things. There is also a Python
    client API that wraps the REST calls conveniently for you.

    Please see http://cloudera.github.com/cm_api/ for download links and
    documentation.
