Updating the Configuration of the Installed Client

Updated at: Aug 17, 2021 GMT+08:00


The cluster provides a client for you to connect to a server, view task results, or manage data. If you modify service configuration parameters on FusionInsight Manager and restart the service, you need to download and install the installed client again or use the configuration file to update the client.


You have installed the client.


Method 1:

  1. Log in to FusionInsight Manager. Click the wanted cluster from the Cluster drop-down list..
  2. Choose More > Download Client > Configuration Files Only.

    The generated compressed file contains the configuration files of all services.

  3. Determine whether a configuration file needs to be generated on the cluster node.

    • If yes, select Save to Path, and click OK to generate the client file. By default, the client file is generated in /tmp/FusionInsight-Client on the active management node. You can also store the client file in other directories, and user omm has the read, write, and execute permissions on the directories. Then, go to 4.
    • If no, click OK, specify a local save path, and download the complete client. Wait until the download is complete, and go to 4.

  4. Use WinSCP to save the compressed file to the installation directory of the client as the client installation user, such as /opt/hadoopclient.
  5. Decompress the software package.

    Run the following commands to enter into the directory where the client is installed, and decompress the file to a local directory. For example, the downloaded client file is FusionInsight_Cluster_1_Services_Client.tar.

    cd /opt/hadoopclient

    tar -xvf FusionInsight_Cluster_1_Services_Client.tar

  6. Verify the software package.

    Run the sha256sum command to verify the retrieved file. Check whether the command output is consistent with the information in the sha256 file. Example command:

    sha256sum -c FusionInsight_Cluster_1_Services_ClientConfig_ConfigFiles.tar.sha256

    FusionInsight_Cluster_1_Services_ClientConfig_ConfigFiles.tar: OK     

  7. Decompress the package to obtain the configuration file.

    tar -xvf FusionInsight_Cluster_1_Services_ClientConfig_ConfigFiles.tar

  8. Run the following command in the client installation directory to update the client using the configuration file:

    sh Client installation directory Directory where the configuration file is located

    For example, run the following command:

    sh /opt/hadoopclient /opt/hadoopclient/FusionInsight_Cluster_1_Services_ClientConfig_ConfigFiles

    If the following information is displayed, the configurations have been updated successfully.

    Succeed to refresh components client config.

Method 2:

  1. Log in to the client installation node as user root.
  2. Go to the client installation directory, for example, /opt/Bigdata/client and run the following command to update the configuration file:

    cd /opt/Bigdata/client


  3. Enter the username and password of the FusionInsight Manager administrator and the floating IP address of FusionInsight Manager.
  4. Enter the names of the components whose configuration needs to be updated. Use commas (,) to separate the component names. Press Enter to update the configurations of all components if necessary.

    If the following information is displayed, the configurations have been updated successfully.

    Succeed to refresh components client config.
