ayushtkn commented on issue #11005: [FLINK-15838] Dangling CountDownLatch.await(timeout) URL: https://github.com/apache/flink/pull/11005#issuecomment-581787826 Hi @leventov that completely makes sense. In Apache Hadoop too, if the method return value is ignored we get a checkstyle warning in the build report, but the checkstyles in hadoop, doesn't fail the build. So, in some cases where the response isn't of any use, only the execution of the method is important, then in that case the committer has the liberty to ignore the checkstyle warning. But in Flink the build itself will fail, so cases where the response of the method isn't needed just the execution is important it can create problem. if you say we can create a follow-up jira for this rule integration and discuss..
