  • Verified that your Cloudera Observability On-Premises cluster is running a supported version of Cloudera Manager and the Cloudera Data Platform (CDP) and that your Workload clusters are running a supported version of Cloudera Manager and Cloudera Platform.
  • Recorded the Cloudera Manager host name of the server that contains an installation of Cloudera Observability On-Premises, as this value is required during the upgrade process.
  • Downloaded the 3.5.2 version of the Cloudera Observability On-Premises installation parcel and checksum from the Cloudera Downloads website.
  • Downloaded the 3.5.2 version of the Cloudera Observability On-Premises installation CSD (.jar) file from the Cloudera Downloads website.
  • Stopped the Cloudera Observability On-Premises service and its services.
  1. Log in to Cloudera Manager and verify that the Cloudera Observability On-Premises Service and its services are stopped.
  2. Do the following:
    1. In a terminal, SSH into the Cloudera Manager host server.
    2. Copy the downloaded parcel (.parcel) and its checksum (.sha) file to the /opt/cloudera/parcel-repo directory of the Cloudera Manager Server on the Cloudera Observability On-Premises cluster.
    3. Copy the downloaded CSD (.jar) file to the /opt/cloudera/csd directory of the Cloudera Manager Server on the Cloudera Observability On-Premises cluster.
    4. Delete or remove the existing Cloudera Observability On-Premises 3.4.4 CSD (.jar) file.
  3. In the /opt/cloudera/parcel-repo directory, set the ownership of the parcel and checksum files to cloudera-scm:cloudera-scm.
  4. In the /opt/cloudera/csd directory, set the ownership of the CSD JAR file to cloudera-scm:cloudera-scm.
  5. In a supported web browser on the Cloudera Observability On-Premises cluster, log in to Cloudera Manager.
  6. In Cloudera Manager, select Clusters, Parcels, and then Distribute.
