Upgrading Arcadia Enterprise Using Ambari Stacks

Developer Note. We do not test or certify rolling upgrades of clusters or operating systems; they may or may not work.

To upgrade an existing Arcadia Enterprise service to a newer version, perform these tasks:

Removing Arcadia Service
Updating Arcadia File Sources
Adding Arcadia Service

Here, note the place holders:

user_name is the account of the user with administrative privileges (and root access) and password it its password
ambari_hostname is the name of the Ambari Stacks host and port is the port used, typically 8080
cluster_name is the name of the cluster
hdp_version is the version of the HDP, such as 2.3, 2.4, 2.6, and so on
release_tarball_id is the suffix of the tar file name, such as 4.0.0.0_1491274848-1

Removing Arcadia Service

Follow these steps the remove Arcadia service from Ambari Stacks, without removing the installed rpm:

$ curl -u username:password
       -i -H 'X-Requested-By: ambari' 
       -X DELETE  http://ambari_hostname:port/api/v1/clusters/cluster_name/services/ARCADIAENTERPRISE

You should see a system response that looks somewhat like this:

Updating Arcadia File Sources

Update the Arcadia file sources to the new version; this involves removing the old folder and copying the new folder to its location.

Run the following commands at the root:

Remove the folder that contains the older Arcadia source files from the /services directory.

$ sudo rm -rf /var/lib/ambari-server/resources/stacks/HDP/hdp_version/services/ARCADIA-ENTERPRISE

Extract the zipped tar of new Arcadia files.

$ tar -xvzf ARCADIA-ENTERPRISE-release_tarball_id.tar.gz

Copy the extracted contents into the /services directory.

$ sudo cp -R ARCADIA-ENTERPRISE /var/lib/ambari-server/resources/stacks/HDP/hdp_version/services/

Re-start the Ambari server.
```
$ sudo service ambari-server restart
```

Adding Arcadia Service

After completing the previous tasks, add Arcadia Enterprise service through the Ambari Stacks UI, as described in Add Arcadia Enterprise to Ambari Services.
