Nanda kumar commented on HDDS-216:
----------------------------------
{{MiniOzoneCluster}} already uses a random port.
{{TestStorageContainerManagerHttpServer}} doesn't use {{MiniOzoneCluster}}, it
starts the http and https servers directly for testing. The fix has to be done
in {{TestStorageContainerManagerHttpServer}}.
{code:java}
conf.set(ScmConfigKeys.OZONE_SCM_HTTP_ADDRESS_KEY, "localhost:0");
{code}
the above code has to be added to the test-case {{testHttpPolicy}}.
> hadoop-hdds unit tests should use randomized ports

> Key: HDDS-216
> URL: https://issues.apache.org/jira/browse/HDDS-216
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: test
> Reporter: Arpit Agarwal
> Priority: Major
> Labels: newbie, test
> Fix For: 0.2.1
>
>
> MiniOzoneCluster should use randomized ports by default, so individual tests
> don't have to do anything to avoid port conflicts at runtime. e.g.
> TestStorageContainerManagerHttpServer fails if port 9876 is in use.
