Upgrading to the 3.6.2 version of Cloudera Observability

Steps for upgrading to the 3.6.2 version of Cloudera Observability.

Describes the pre-tasks and steps for upgrading to Cloudera Observability version 3.6.2.
These steps assume that you have:
  • Scheduled the upgrade and informed your users of the Cloudera Observability service interruption.
  • Verified that your Cloudera Observability cluster is running a supported version of Cloudera Manager and the Cloudera and that your Workload clusters are running a supported version of Cloudera Manager and Cloudera Platform.
  • Recorded the Cloudera Manager hostname of the server that contains an installation of Cloudera Observability, as this value is required during the upgrade process.
  • Downloaded the 3.6.2 version of the Cloudera Observability installation parcel and checksum from the Cloudera Downloads website.
  • Downloaded the 3.6.2 version of the Cloudera Observability installation CSD (.jar) file from the Cloudera Downloads website.
  • Stopped the Cloudera Observability service and its services.
  1. Log in to Cloudera Manager and verify that the Cloudera Observability 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 cluster.
    3. Copy the downloaded CSD (.jar) file to the /opt/cloudera/csd directory of the Cloudera Manager Server on the Cloudera Observability cluster.
    4. Delete or remove the existing Cloudera Observability On-Premises 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. From the Cloudera Manager Host, restart the Cloudera Manager Server by entering the following command: 
    service cloudera-scm-server restart
  6. In a supported web browser on the Cloudera Observability cluster, log in to Cloudera Manager.
  7. In Cloudera Manager, select Clusters, Parcels, and then Distribute.
    In the list of parcels, the latest version appears with a gray Distribute label.
  8. Activate the Cloudera Observability installation files by selecting Activate Only. Do not restart.
  9. In the Cloudera Manager UI, navigate to the Observability service and then from the Actions menu, do the following:
    1. Select each of the following actions to create the required directories in HDFS on the Cloudera Observability cluster as follows:
      • Create the cloudera-dbus Directory
      • Create the cloudera-sigma-sdx-payloads Directory
      • Create the cloudera-sigma-pse-extended Directory
      • Create the cloudera-sigma-partial-pse Directory
      • Create the cloudera-sigma-olap Directory
      • Create the cloudera-sigma-processor-files Directory
      • Create cloudera-sigma-olap-impala Directory
      • Create cloudera-sigma-exported-reports Directory
    2. Select Create directories on HDFS on OLAP to create directories in HDFS for OLAP by Analytic Database Server.
    3. Select Upgrade Database Schemas to upgrade the database schemas.
    4. Select Restart to restart the Cloudera Observability service.
  10. After all the roles have started, from the Actions menu, select Repair Workload Database.
