Installing OmniOperator

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

1. Upload OmniOperator-related packages obtained in Obtaining Software to the /opt/omni-operator/ directory on the management and compute nodes.
2. Go to the /opt/omni-operator/ directory and decompress the packages.

   cd /opt/omni-operator/
   unzip BoostKit-omniop_1.1.0.zip
   tar -zxvf boostkit-omniop-operator-1.1.0-aarch64.tar.gz

3. Copy OmniOperator-related files to the /opt/omni-operator/lib directory and set the permission on the software packages in the directory to 550.

   cd /opt/omni-operator/boostkit-omniop-operator-1.1.0-aarch64
   cp -r include libboostkit* boostkit-omniop* config.h libsecurec.so /opt/omni-operator/lib/
   chmod 550 /opt/omni-operator/lib/*

4. Create a conf folder in /opt/omni-operator. Add the omni.conf file to the folder and set the permission on the configuration file to 640. This file is used to set OmniOperator configuration items.

   cd /opt/omni-operator
   mkdir conf
   cd conf
   touch omni.conf
   chmod 640 omni.conf

5. Add the following content to the /opt/omni-operator/conf/omni.conf file:
   1. Open /opt/omni-operator/conf/omni.conf.

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

   2. Added the configuration content.

      enableHMPP=true  // true indicates that HMPP is enabled, and false indicates that HMPP is disabled (disabled by default). You can enable or disable HMPP as required.
      #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.
6. Use vim to open the ~/.bashrc file and add LD_LIBRARY_PATH to the file to update environment variables.
   1. Open the ~/.bashrc file.

      vim ~/.bashrc

   2. Add LD_LIBRARY_PATH to update environment variables.

      export LD_LIBRARY_PATH=/opt/omni-operator/lib:/usr/local/lib/HMPP:$LD_LIBRARY_PATH

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

      source ~/.bashrc
