A specification for this change was submitted for review in https://review.openstack.org/#/c/151279 - HP Vertica Community Edition supports upto a 3-node cluster. - HP Vertica requires a minimum of 3 nodes to achieve fault tolerance. - This patchset provides ability to launch HP Vertica 3-node cluster. - The cluster-show API, would also list the IPs of underlying instances. Code Added: - Added API strategy, taskmanager strategy, and guestagent strategy. - Included unit tests. Workflow for building Vertica cluster is as follows: - Guest instances are booted using new API strategy which then sends control to taskmanager strategy for further communication and guestagent API execution. - Once the guest instances are active in nova, they receive "prepare" message and following steps are performed: - Mount the data disk on device_path. - Check if vertica packages have been installed, install_if_needed(). - Run Vertica pre-install test, prepare_for_install_vertica(). - Get to a status BUILD_PENDING. - Cluster-Taskmanager strategy waits for all the instances in cluster to get to BUILD_PENDING state. - Once all instances in a cluster get to BUILD_PENDING state, taskmanager first, configures passwordless ssh for os-users(root, dbadmin) with the help of guestagent APIs get_keys and authroize_keys. - Once passwordless ssh has been configured, the taskmanager calls install_cluster guestagent API, which installs cluster on member instances and creates a database on the cluster. - Once this method finishes its job then taskmanager calls another guestagent API cluster_complete to notify cluster member of completion of cluster creation. New Files: - A new directory, vertica, has been created, for api, taskmanager, guestagent strategies under trove/common/strategies/cluster/experimental. - Unit-tests for cluster-controller, api and taskmanager code.

Trove
Trove is Database as a Service for Open Stack.
Usage for integration testing
If you'd like to start up a fake Trove API daemon for integration testing with your own tool, run:
$ ./tools/start-fake-mode.shStop the server with:
$ ./tools/stop-fake-mode.shTests
To run all tests and PEP8, run tox, like so:
$ toxTo run just the tests for Python 2.7, run:
$ tox -epy27To run just PEP8, run:
$ tox -epep8To generate a coverage report,run:
$ tox -ecover(note: on some boxes, the results may not be accurate unless you run it twice)
If you want to run only the tests in one file you can use testtools e.g.
$ python -m testtools.run trove.tests.unittests.python.module.path
