             Summary: Smoketest to write data on network aware cluster
                 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


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.
