Create a Storm Policy

To add a new policy to an existing Storm service:

  1. On the Service Manager page, select an existing service under Storm.

    The List of Policies page appears.

  2. Click Add New Policy.

    The Create Policy page appears.

  3. Complete the Create Policy page as follows:

    Table 6.3. Policy Details



    Policy NameEnter an appropriate policy name. This name is cannot be duplicated across the system. This field is mandatory.
    Storm TopologyEnter an appropriate Topology Name.
    Description(Optional) Describe the purpose of the policy.
    Audit LoggingSpecify whether this policy is audited. (De-select to disable auditing).

    Table 6.4. Allow Conditions



    Select Group

    Specify the group to which this policy applies. To designate the group as an Administrator for the chosen resource, specify Admin permissions. (Administrators can create child policies based on existing policies).

    The public group contains all users, so granting access to the public group grants access to all users.

    Select UserSpecify a particular user to which this policy applies (outside of an already-specified group) OR designate a particular user as Admin for this policy. (Administrators can create child policies based on existing policies).
    PermissionsAdd or edit permissions: Read, Write, Create, Admin, Select/Deselect All.
    Delegate AdminWhen a policy is assigned to a user or a group of users those users become the delegated admin. The delegated admin can update, delete the policies. It can also create child policies based on the original policy (base policy).

    Since Storm does not provide a command line methodology for assigning privileges or roles to users, the User and Group Permissions portion of the Storm Create Policy form is especially important.

    Table 6.5. Storm User and Group Permissions

    File uploadAllows a user to upload files.
    Get Nimbus ConfAllows a user to access Nimbus configurations.
    Get Cluster InfoAllows a user to get cluster information.

  4. You can use the Plus (+) symbol to add additional conditions. Conditions are evaluated in the order listed in the policy. The condition at the top of the list is applied first, then the second, then the third, and so on.
