Upgrade SmartSense

If you have previously installed SmartSense as part of your Ambari-managed cluster, you must perform some manual steps to upgrade. A SmartSense upgrade includes ensuring that SmartSense is in Maintenance Mode, upgrading binaries on the HST server and agents on every node in your cluster, and upgrading the Ambari service and view.

1. Upgrade binaries on the HST server and all HST agents on every node in the cluster, assuming that the Ambari repository is configured on all nodes in the cluster:

   • RHEL or CentOS

     yum clean all
     yum info smartsense-hst

     In the info output, visually validate that there is an available version containing "1.5.x”:

     yum upgrade smartsense-hst

   • SLES

     zypper clean
     zypper info smartsense-hst

     In the info output, visually validate that there is an available version containing "1.5.x":

     zypper up smartsense-hst

   • Ubuntu or Debian

     apt-get clean all
     apt-get update
     apt-cache show smartsense-hst | grep Version 

     In the info output, visually validate that there is an available version containing "1.5.x":

     apt-get install smartsense-hst 

2. Upgrade Ambari service and Ambari view by running the hst upgrade-ambari-servicecommand as the root user from the machine running the Ambari server. You can run the command in the interactive or non-interactive mode:

   Interactive mode example:

   # hst upgrade-ambari-service
   Please enter Ambari Server hostname (ambari-server.hortonworks.local):
   Please enter Ambari Server port (8080):
   Please enter Ambari admin user id (admin):
   Please enter password for admin:

   Installing new view ...
   Removing deprecated alerts ...
   Updating SmartSense configurations in Ambari ...
   
   SmartSense service upgrade completed!
   NOTE: It is required to restart Ambari Server for changes to reflect. Please restart ambari using 'ambari-server restart'

   Non-interactive mode example:

   # hst upgrade-ambari-service -u admin -p 8080 -H ambari-server.hortonworks.local -P MySecurePassword123
   Un-installing old view ...
   Installing new view ...
   Removing deprecated alerts ...
   Updating SmartSense configurations in Ambari ...
   SmartSense service upgrade completed!
   NOTE: It is required to restart Ambari Server for changes to reflect. Please restart ambari using 'ambari-server restart'

3. Restart the Ambari server:

   # ambari-server restart

4. If you have HST Gateway installed, you need to also upgrade your HST Gateway:
   1. If the HST Gateway is installed on the same node as HST Server or HST Agent, then the HST Gateway will get upgraded along with them.
   2. If the HST Gateway is a standalone node outside of the cluster, perform upgrade steps described in Upgrade SmartSense Gateway in the SmartSense documentation.
