> Key: HDDS-3084
> URL: https://issues.apache.org/jira/browse/HDDS-3084
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: SCM
> Affects Versions: 0.6.0
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> It would be good to create a smoke test which:
> 1. Writes some data on a network aware cluster
> 2. Stops 1 rack and ensures the data is still readable
> 3. Restart the rack and stop the other rack and again check the data is readable
> That way we can have some confidence the data is being written to both racks OK.
> One issue with a test like this on a small cluster, is that there is a high chance the data will end up on 2 racks naturally, even if no network topology is configured. If that was the case, we would expect intermittent test failures.
> However, if network topology is working fine, then we would not expect any failures.
