[jira] [Created] (FLINK-10637) Start MiniCluster with random REST port

Till Rohrmann created FLINK-10637:
-------------------------------------

             Summary: Start MiniCluster with random REST port
                 Key: FLINK-10637
                 URL: https://issues.apache.org/jira/browse/FLINK-10637
             Project: Flink
          Issue Type: Improvement
          Components: Tests
    Affects Versions: 1.6.1, 1.5.4, 1.7.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.6, 1.6.3, 1.7.0


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.
