--------------------------------------
[~godfreyhe] is this is a valid issue or can we close it?
> 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 / Planner
> Affects Versions: 1.11.0
> Reporter: godfrey he
> Priority: Minor
> Labels: auto-deprioritized-major
>
> 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 ?
