> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Reporter: Mingliang Liu

> Priority: Major

>
> Currently we don't delete the local storage when closing
> {{MiniOzoneCluster}}, which will cause creating volume with the same name to
> fail, even in a new JVM process. Let's delete the local storage files:
> {{/tmp/ozone/metadata.db}} and {{/tmp/ozone/user.db}} when closing.
> Please note this is not a complete solution. As the {{OzoneMetadataManager}}
> currently is a singleton, we are not able to create two independent
> MiniOzoneCluster in a single JVM. Data maybe shared unexpectedly. Let's
> address that in another JIRA, if needed.
