Install ThoughtSpot Clusters on the SMC Appliance

Install your clusters on the SMC appliance.

Install the cluster using the ThoughtSpot software release bundle. Installation takes approximately one hour. Make sure you can connect to ThoughtSpot remotely. If you can, you can run the installer on your local computer.

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

Follow the steps in this checklist to install your cluster.

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.

    1. 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.

    2. Launch a screen session. Use screen to ensure that your installation does not stop if you lose network connectivity.

       $ screen -S DEPLOYMENT
    3. Create the cluster. + Run tscli cluster create <release-number>.

       $ tscli cluster create <release-number>.tar.gz
    4. 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.

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.

Log in to any node to check the current cluster status, using the 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 above. 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.

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:

    • Click Advanced

    • Click Proceed

  4. The ThoughtSpot sign-in page appears.

  5. In the ThoughtSpot sign-in window, enter admin credentials, and click Sign in. If you do not 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, advanced lean configuration is required before loading any data into ThoughtSpot. After installing the cluster, contact ThoughtSpot Support for assistance with this configuration.

Additional resources

As you develop your expertise in SMC cluster installation, we recommend the following ThoughtSpot U course:

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.
