Summary: Cleaning up local storage when closing MiniOzoneCluster
Key: HDFS-11903
URL: https://issues.apache.org/jira/browse/HDFS-11903
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Reporter: Mingliang Liu
Assignee: Mingliang Liu
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.
