adoroszlai opened a new pull request #1358: HDDS-2045. Partially started 
compose cluster left running
URL: https://github.com/apache/hadoop/pull/1358
 
 
   ## What changes were proposed in this pull request?
   
   If any container in the sample cluster [fails to 
start](https://github.com/elek/ozone-ci/blob/5c64f77f3ab64aed0826d8f40991fe621f843efd/pr/pr-hdds-2026-p4f6m/acceptance/output.log#L24),
 all successfully started containers are left running.  This 
[prevents](https://github.com/elek/ozone-ci/blob/5c64f77f3ab64aed0826d8f40991fe621f843efd/pr/pr-hdds-2026-p4f6m/acceptance/output.log#L59)
 any further acceptance tests from normal completion.  This is only a minor 
inconvenience, since acceptance test as a whole fails either way.
   
   This change makes sure the cluster is stopped if startup fails.
   
   https://issues.apache.org/jira/browse/HDDS-2045
   
   ## How was this patch tested?
   
   Temporarily added fake failures in `start_docker_env` and 
`wait_for_datanodes`, and verified that the cluster is stopped:
   
   ```
   $ ./test.sh
   Removing network ozone_default

   ```
   
   Verified that the test succeeds without the fake failure.
