[jira] [Commented] (BEAM-8901) add experimental flag for reusing flink local environment

    [ https://issues.apache.org/jira/browse/BEAM-8901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16989263#comment-16989263 ] 

Robert Bradshaw commented on BEAM-8901:
---------------------------------------

Is it not possible to reclaim the resources by shutting it down cleanly? (Re-use may still be desirable if it's expensive to bring up and down of course, but if it's cheap, making tests hermetic is another benefit.)

> Flink job server launches a new mini cluster every time we run the pipeline on Flink local environment. To prevent OOM, we need to reuse existing Flink local environment if possible.
