Chesnay Schepler commented on FLINK-10637:
------------------------------------------

The MiniClusterResource already sets the rest port to 0. https://github.com/apache/flink/blob/master/flink-test-utils-parent/flink-test-utils/src/main/java/org/apache/flink/test/util/MiniClusterResource.java#L158

> The {{MiniCluster}} picks a random port for the {{RpcService}} but not for the REST server endpoint. Due to this it falls back to {{8081}}. This can lead to port conflicts if tests are executed concurrently.
> I propose to rename the {{MiniClusterResource}} into {{MiniClusterResourceWithRestClient}} and add a new {{MiniClusterResource}} which only starts a {{MiniCluster}} with the REST port set to 0.
