----------------------------------

             Summary: reuse MiniCluster in table integration test class ?
                 Key: FLINK-18717
                 URL: https://issues.apache.org/jira/browse/FLINK-18717
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Legacy Planner, Table SQL / Planner
    Affects Versions: 1.11.0
            Reporter: godfrey he


before 1.11, {{MiniCluster}} can be reused in each integration test class. (see TestStreamEnvironment#setAsContext)
In 1.11, after we correct the execution behavior of TableEnvironment, StreamTableEnvironment and BatchTableEnvironment (see [FLINK-16363|https://issues.apache.org/jira/browse/FLINK-16363], [FLINK-17126|https://issues.apache.org/jira/browse/FLINK-17126]), MiniCluster will be created for each test case even in same test class (see {{org.apache.flink.client.deployment.executors.LocalExecutor}}). It's better we can reuse {{MiniCluster}} like before. One approach is we provide a new kind of  MiniCluster factory (such as: SessionMiniClusterFactory) instead of using  {{PerJobMiniClusterFactory}}. WDYT ?
