-----------------------------------------
exploy opened a new pull request #4015: [AIRFLOW-2789] Create single node
cluster
URL: https://github.com/apache/incubator-airflow/pull/4015
Make sure you have checked _all_ steps below.
### Jira
- [ ] My PR addresses the following [Airflow
Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references
them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
- https://issues.apache.org/jira/browse/AIRFLOW-XXX
- In case you are fixing a typo in the documentation you can prepend your
commit with \[AIRFLOW-XXX\], code changes always need a Jira issue.
### Description
In GCP, it is possible to set up [Single node
clusters](https://cloud.google.com/dataproc/docs/concepts/configuring-clusters/single-node-clusters)
Since the minimal size of the cluster (without this modification) is 3 (one
master + two workers). It may be very helpful while doing, for example,
small-scale non-critical data processing or building proof-of-concept.
### Tests
- [x] My PR adds the following unit tests `test_build_single_node_cluster`
and `test_init_with_single_node_and_non_zero_workers`
### Commits
- [x] My commits all reference Jira issues in their subject lines, and I
have squashed multiple commits if they address the same issue. In addition, my
commits follow the guidelines from "[How to write a good git commit
message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Documentation
- [x] In case of new functionality, my PR adds documentation that describes
how to use it.
- When adding new operators/hooks/sensors, the autoclass documentation
generation needs to be added.
### Code Quality
- [ ] Passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
