Configuring the connection

  1. Click Run to open its view and then click
    Storm configuration to set up the
    connection to the Storm system to be used.

  2. In the Storm node roles
    area, indicate the locations of the Nimbus server and the DRPC endpoint of the
    Storm cluster to be used:

    Option/Fields

    Description

    Local mode

    Select this check box to build the Storm environment within the
    Studio. In this situation, the Storm Job you are designing is run
    locally within the Studio and you do not need to define any specific
    Nimbus and DRPC endpoint addresses.

    Nimbus host and
    Port

    In these two fields, enter the location of the Storm Nimbus server
    and its port number, respectively.

    DRPC endpoint and
    Port

    In these two fields, enter the location of the Storm DRPC endpoint
    and its port number, respectively.
  3. In the Topology name field, enter the
    name you want the Storm system to use for the Storm Job, or topology in
    terms of the Storm, you are designing. It is recommended to use the same
    name as you have named this Storm Job so that you can easily recognize this
    Job even within the Storm system.
  4. Select the Kill existing topology check box to make the
    Storm system stop any topology that has the same name as the Job you are
    designing and want to run.

    If you clear this check box and that Job of the same name is already running in the Storm
    system, the current Job will fail when you send it to Storm to run.
  5. Select the Submit topology check box to submit the
    current Job to the Storm system. This feature is used when you need to send
    a new topology to Storm or used together with the Kill
    existing topology     feature when you need to update a running
    topology in the Storm system.

    If you clear this check box, when you run the current Job, the submission
    of this Job is ignored while the other configuration information is still
    taken into account, for example, killing an existing topology.
  6. Select the Monitor topology after
    submission     check box to monitor the current Storm Job in the
    console of the Run view.

    If you clear this check box, you cannot read the monitoring information in
    the console.
  7. In the Stop monitoring after timeout
    reached     field, enter, without the double quotation marks, the
    numeric value to indicate whether to stop the monitoring when a running
    topology reaches its timeout. The default value is -1, which means no timeout is applied.
  8. Select the Kill topology on quitting Talend Job check
    box to allow the Studio to kill, if it is still running, the current Job
    from the Storm system when you stop this Job from the Studio.

    If you clear this check box, the topology for this Job continues to run in the Storm
    system even though you kill it within the Studio or eventually shut down the
    Studio.
  9. If you need to use any other Storm properties specific to your situation,
    add them to the Storm configuration
    table.
