Arpit Agarwal commented on HDFS-8338:
-------------------------------------
Big +1 for this idea.
I am not sure if there is any FsDatasetImpl functionality that is solely
covered by balancer tests. If so we should add separate tests for it to avoid
losing test coverage.
> SimulatedFSDataset support multiple storages/volumes

> Key: HDFS-8338
> URL: https://issues.apache.org/jira/browse/HDFS-8338
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Walter Su
> Assignee: Walter Su
> Priority: Minor
>
> Some tests(like Mover/Balancer) move block among storages.
> The tests use FsDatasetImpl because SimulatedFSDataset doesn't support
> multiple storages.
> The tests can be faster if they utilize SimulatedFSDataset, only if
> SimulatedFSDataset support multiple storages.
