Uninstalling OmniOperator

Perform the following steps on the management node and all compute nodes. Ensure that no task is being executed on the OmniOperator upper-layer engine.

Delete the configuration file, dependency SO files, and OmniOperator-related files. For details about how to uninstall the HMPP dependencies, see 3. The following uses the /opt/omni-operator/conf and /opt/omni-operator/lib installation directories as an example.

1. Delete the conf folder.

   rm -rf /opt/omni-operator/conf

2. Go to the /opt/omni-operator/lib directory and delete the SO dependency file and OmniOperator-related files.

   cd /opt/omni-operator/lib
   rm -rf libjemalloc.so.2 libLLVM-12.so
   rm -rf include libboostkit-omniop* boostkit-omniop* config.h libsecurec.so

   1. Open the ~/.bashrc file.

      vim ~/.bashrc

   2. Press i to enter the insert mode. Delete the LD_LIBRARY_PATH information of OmniOperator and update the environment variables.
   3. Press Esc, type :wq!, and press Enter to save the file and exit.
