Install ThoughtSpot clusters on the SMC appliance

Install your clusters on the SMC appliance using the ThoughtSpot software release bundle. Installation takes approximately one hour. Make sure you can connect to ThoughtSpot remotely. You may be able to run the installer on your local computer.

ThoughtSpot has stopped selling and renewing hardware appliance contracts. See CentOS end-of-life announcement for more information, and alternative deployment options.

ThoughtSpot Training

  • For best results when installing ThoughtSpot on the SMC appliance, we recommend that you take the following ThoughtSpot U course: Create a Cluster.

  • See other training resources at ThoughtSpot U.

Refer to your welcome letter from ThoughtSpot to find the link to download the release bundle. If you haven’t received a link to download the release bundle, open a support ticket with ThoughtSpot Support.

Step 1: Run the installer

❏

Step 2: Check cluster health

❏

Step 3: Finalize installation

Step 1. Run the Installer

  1. Copy the downloaded release bundle to /export/sdb1/TS_TASKS/install. Run scp <release-number>.tar.gz admin@<hostname>:/export/sdb1/TS_TASKS/install/<file-name>.

    Note the following parameters:

    release-number

    is the release number of your ThoughtSpot installation, such as 6.0, 5.3, 5.3.1, and so on.

    hostname

    is your specific hostname.

    file-name

    is the name of the tarball file on your local machine.

    $ scp <release-number>.tar.gz admin@<hostname>:/export/sdb1/TS_TASKS/install/<file-name>
    You can use another secure copy method, if you prefer a method other than the scp command.

  2. Alternatively, use tscli fileserver download-release to download the release bundle.

    You must configure the fileserver by running tscli fileserver configure before you can download the release.

    $ tscli fileserver download-release <release-number> --user <username> --out <release-location>

    Note the following parameters:

    release-number

    is the release number of your ThoughtSpot instance, such as 5.3, 5.3.1, 6.0, and so on.

    username

    is the username for the fileserver that you set up earlier, when configuring the fileserver.

    release-location

    is the location path of the release bundle on your local machine. For example, /export/sdb1/TS_TASKS/install/6.0.tar.gz.

  3. Verify the checksum to ensure you have the correct release.

    Run md5sum -c <release-number>.tar.gz.MD5checksum.

     $ md5sum -c <release-number>.tar.gz.MD5checksum

    Your output says ok if you have the correct release.

  4. Launch a screen session. Use screen to ensure that your installation doesn’t stop if you lose network connectivity.

     $ screen -S DEPLOYMENT

  5. Take a machine snapshot prior to the release deployment, as a best practice.

  6. Create the cluster. Run:

     $ tscli cluster create <release-number>.tar.gz

  7. Edit the output using your specific cluster information. For more information on this process, refer to Using the tscli cluster create command and Parameters of the cluster create command.

  8. The cluster installer automatically reboots all the nodes after the install. Wait at least 15 minutes for the installation process to complete. The system is rebooting, which takes a few minutes.

    Sign in to any node to check the current cluster status by running this command:

    tscli cluster status

Step 2. Check cluster health

After you install the cluster, check its status using the tscli cluster status and tscli cluster check commands.

$ tscli cluster status
Cluster: RUNNING
Cluster name    : thoughtspot
Cluster id      : 1234X11111
Number of nodes : 3
Release         : 6.0
Last update     = Wed Oct 16 02:24:18 2019
Heterogeneous Cluster : False
Storage Type    : HDFS

Database: READY
Number of tables in READY state: 2185
Number of tables in OFFLINE state: 0
Number of tables in INPROGRESS state: 0
Number of tables in STALE state: 0
Number of tables in ERROR state: 0

Search Engine: READY
Has pending tables. Pending time = 1601679ms
Number of tables in KNOWN_TABLES state: 1934
Number of tables in READY state: 1928
Number of tables in WILL_REMOVE state: 0
Number of tables in BUILDING_AND_NOT_SERVING state: 0
Number of tables in BUILDING_AND_SERVING state: 128
Number of tables in WILL_NOT_INDEX state: 0

Ensure that the cluster is RUNNING and that the Database and Search Engine are READY.

Your output may look something like the following listing. Ensure that all diagnostics show SUCCESS.

If tscli cluster check returns an error, it may suggest you run tscli storage gc to resolve the issue. If you run tscli storage gc, note that it restarts your cluster. 
$ tscli cluster check

Step 3: Finalize installation

After the cluster status changes to “Ready,” sign in to the ThoughtSpot application on your browser.

Follow these steps:

  1. Start a browser from your computer.

  2. Enter your secure IP information on the address line.

     https://<IP-address>

  3. If you don’t have a security certificate for ThoughtSpot, you must bypass the security warning to proceed:

    • Select Advanced

    • Select Proceed

  4. The ThoughtSpot sign-in page appears.

  5. In the ThoughtSpot sign-in window, enter admin credentials, and select Sign in. If you don’t know the admin credentials, ask your network administrator. ThoughtSpot recommends changing the default admin password.

    ThoughtSpot’s sign-in window

Lean configuration

For use with thin provisioning only: If you have a small or medium instance type, with less than 100GB of data, you must use advanced lean configuration before loading any data into ThoughtSpot. After installing the cluster, contact ThoughtSpot Support for assistance with this configuration.

Error recovery

Set-config error recovery

If you get a warning about node detection when you run the set-config command, restart the node-scout service.

Your error may look something like the following:

Connecting to local node-scout WARNING: Detected 0 nodes, but found configuration for only 1 nodes.
Continuing anyway. Error in cluster config validation: [] is not a valid link-local IPv6 address for node: 0e:86:e2:23:8f:76 Configuration failed.
Please retry or contact support.

Restart the node-scout service with the following command.

 $ sudo systemctl restart node-scout

Ensure that you restarted the node-scout by running sudo systemctl status node-scout. Your output should specify that the node-scout service is active. It may look something like the following:

$ sudo systemctl status node-scout
   ● node-scout.service - Setup Node Scout service
     Loaded: loaded (/etc/systemd/system/node-scout.service; enabled; vendor preset: disabled)
     Active: active (running) since Fri 2019-12-06 13:56:29 PST; 4s ago

Next, retry the set-config command.

$ cat nodes.config | tscli cluster set-config

The command output should no longer have a warning.
