Uninstalling OmniOperator

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

Assume that the SparkExtension directories are /opt/omni-operator/conf and /opt/omni-operator/lib, and the HiveExtension directory is /opt/omni-operator/hive.

1. Delete the conf and hive folders.

3. Optional: When using OmniOperator on Spark, delete the OmniOperator installation package of HDFS.
