ifndef-SleePy opened a new pull request #9147: [FLINK-11631][test] Harden TaskExecutorITCase
URL: https://github.com/apache/flink/pull/9147
 
 
   ## What is the purpose of the change
   
   * Harden `TaskExecutorITCase#testJobReExecutionAfterTaskExecutorTermination`
   * Harden `TastExecutorITCase#testJobRecoveryWithFailingTaskExecutor`
   
   ## Brief change log
   
   * Improve `MiniCluster` by clearing terminated components in case of an reusing
   * Use a map to keep task managers in `MiniCluster` instead of a list since the task managers might be mutable in some test cases
   * `MiniCluster` exposes more components to `TestingMiniCluster` for enriching testing
   * Replace `terminateTaskExecutor(index)` with `terminateTaskExecutorRandomly()` in `TestingMiniCluster`
   * Add a try-catch for `TastExecutorITCase#testJobRecoveryWithFailingTaskExecutor` to avoid unexpected exception caused by terminating task executor
