Running Workers as Users

In Storm secure mode, workers can run as the user (owner of the topology) who deployed the topology. To enable, complete the following steps:

  1. Make sure all users who are going to deploy topologies have a UNIX account on all of the Storm nodes. Workers will run under the UNIX account for topologies deployed by the user.

    Example: For user testuser1 and principal testuser1/c6401.ambari.apache.org, make sure there is a corresponding testuser1 UNIX account.

  2. Add the following configuration under "Custom storm-site" in the Ambari Storm configuration screen:

    supervisor.run.worker.as.user : true

  3. Restart Storm components.
