tillrohrmann opened a new pull request #6899: [FLINK-10637] Use MiniClusterResource for tests in flink-runtime
URL: https://github.com/apache/flink/pull/6899
 
 
   ## What is the purpose of the change
   
   Rename MiniClusterResource into MiniClusterWithClientResource and move base functionality
   in the form of MiniClusterResource into flink-runtime. The new base class simply starts a
   MiniCluster with random ports.
   
   Moreover, this commit lets almost all tests in flink-runtime use the MiniClusterResource
   to guarantee that there are no port conflicts between concurrently executed tests.
