    INFORMATICA BDM
    from the list of services.
  2. Click the
    Service Actions
    dropdown menu and select
    Delete Service
    .

    Ambari stops the Big Data Management service and deletes it from the listing of available services.
    To fully delete Big Data Management from the cluster, continue with the next steps.
  4. In a command window, delete the
    INFORMATICABDM
    folder from the following directory on the name node of the cluster:
    /var/lib/ambari-server/resources/stacks/<Hadoop distribution>/<Hadoop version>/services/
  5. Delete the
    INFORMATICABDM
    folder from the following location on all cluster nodes where it was installed:
    /var/lib/ambari-agent/cache/stacks/<Hadoop distribution>/<Hadoop version>/services
  6. Perform the following steps to remove RPM binary files:
    1. Run the following command to determine the name of the RPM binary archive:
      rpm -qa |grep Informatica
    2. Run the following command to remove RPM binary files:
      rpm -ev <output_from_above_command>
      For example:
      rpm -ev InformaticaHadoop-10.1.1-1.x86_64
  7. Repeat the previous step to remove RPM binary files from each cluster node.
  8. Delete the following directory, if it exists, from the name node and each client node:
    /opt/Informatica/
    .
  9. Repeat the last step on each cluster node where Big Data Management was installed.
