What is the "ELASTIC_ENDPOINT"? #219

When I tried that tuitorial(https://github.com/logicalclocks/hopsworks-tutorials/blob/master/advanced_tutorials/recommender-system/3_build_index.ipynb), I met that error. The logs: Traceback (most recent call last): File “/root/hopsworks/recommender-system/build_index.py”, line 55, in client = OpenSearch(**opensearch_api.get_default_py_config()) File “/kvm/miniconda3/envs/hopsworks/lib/python3.9/site-packages/hopsworks/core/opensearch_api.py”, line 66, in get_default_py_config url = furl(self._get_opensearch_url()) File “/kvm/miniconda3/envs/hopsworks/lib/python3.9/site-packages/hopsworks/core/opensearch_api.py”, line 33, in _get_opensearch_url return os.environ[constants.ENV_VARS.ELASTIC_ENDPOINT_ENV_VAR] File “/kvm/miniconda3/envs/hopsworks/lib/python3.9/os.py”, line 679, in getitem raise KeyError(key) from None KeyError: ‘ELASTIC_ENDPOINT’

I am confused about the ELASTIC_ENDPOINT, what is it , and how to fix it? help!

If you are running this on app.hopsworks.ai, it won't work. Currently, this example only works when run as a job on a Hopsworks cluster. In that case, we set the ELASTIC_ENDPOINT env variable, which points to OpenSearch in Hopsworks.
