Configuring the HAF Service
On an offload node, run the following command to configure the HAF service:
su -s /bin/bash - haf -c "haf-tool service -j <jar_file> -f <main_func> -x <jvm_config> --timeout <timeout_value> --classpath <classpath_dir>"
- For the first configuration, use --start. In the OmniData scenario, the configuration has been performed and the service has been restarted during the deployment and installation. For details, see Installing OmniData.
- It is recommended that the jar_file&classpath_dir directory be in run/haf_user. If the directory is not in run/haf_user, ensure that the haf_user user has the read and execute permissions on related files.
- After the configuration is complete, run su -s /bin/bash - haf -c "haf-tool service --restart" to restart the service for the configuration to take effect.
