found a workaround for though
```python
path =
f"gs://goog-dataproc-initialization-actions-{self.cfg.get('region')}/python/pip-install.sh"
cluster_config = ClusterGenerator(
project_id=self.cfg.get('project_id'),
...........
init_actions_uris=[
path
],
metadata={'PIP_PACKAGES': 'pyyaml requests pandas openpyxl'},
properties=properties,
dag=dag
).make()
return DataprocClusterCreateOperator(
task_id='create_dataproc_cluster',
cluster_name='my-cluster',
project_id=self.cfg.get('project_id'),
region=self.cfg.get('region'),
cluster_config=cluster_config,
dag=dag
)
```
@turbaszek @mik-laj @potiuk , I couldn't able to find an example where i
will use new metadata field ( changed from DICT to Sequence[Tuple[str, str]])
for DataprocClusterCreateOperator() or DataprocCreateClusterOperator() for
initialisations scripts installing PIP_PACKAGES.
any time i tried to pass **[('PIP_PACKAGES', 'pyyaml requests pandas
openpyxl')]** to metadata field, I get invalid metadata.
How does this supposed to be passed, I couldn't able to find any guide in
the docs as well?
