The following operations must be performed on the management node and all compute nodes.

1. Upload the previously mentioned packages to the /opt/omni-operator/hive-udf directory on management and compute nodes.
2. Decompress the related packages.

   unzip udf.zip
   rm -f udf.zip
   unzip conf.zip
   rm -f conf.zip

3. In the /opt/omni-operator/conf/omni.conf file, update the following content:
   1. Open /opt/omni-operator/conf/omni.conf.

      vim /opt/omni-operator/conf/omni.conf

   2. Updated the UDF configuration.

      enableBatchExprEvaluate=false    // false indicates expression row-by-row processing and true indicates that expression bath processing.
      hiveUdfPropertyFilePath=/opt/omni-operator/hive-udf/udf.properties   // UDF trustlist file path.
      hiveUdfDir=/opt/omni-operator/hive-udf/udf   // Hive UDF JAR file directory.

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
4. Use vim to open the ~/.bashrc file and add LD_LIBRARY_PATH to the file to update environment variables.

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
   4. Update the environment variables.

      source ~/.bashrc

You can customize the example names of the udf.zip and conf.zip packages based on your service requirements.
