Till Rohrmann commented on FLINK-16279: --------------------------------------- But shouldn't we also report a {{FAILED}} state back to the client? > Per job Yarn application leak in normal execution mode. > ------------------------------------------------------- > > Key: FLINK-16279 > URL: https://issues.apache.org/jira/browse/FLINK-16279 > Project: Flink > Issue Type: Bug > Components: Client / Job Submission, Runtime / Coordination > Affects Versions: 1.10.0 > Reporter: Wenlong Lyu > Priority: Major > > I run a job in yarn per job mode using {{env.executeAsync}}, the job failed > but the yarn cluster didn't be destroyed. > After some research on the code, I found that: > when running in attached mode, MiniDispatcher will never set > {{shutDownfuture}} before received a request from job client. > {code} > if (executionMode == ClusterEntrypoint.ExecutionMode.NORMAL) { > // terminate the MiniDispatcher once we served the > first JobResult successfully > jobResultFuture.thenAccept((JobResult result) -> { > ApplicationStatus status = > result.getSerializedThrowable().isPresent() ? > ApplicationStatus.FAILED : > ApplicationStatus.SUCCEEDED; > LOG.debug("Shutting down per-job cluster > because someone retrieved the job result."); > shutDownFuture.complete(status); > }); > } > {code} > However, when running in async mode(submit job by env.executeAsync), there > may be no request from job client because when a user find that the job is > failed from job client, he may never request the result again. -- This message was sent by Atlassian Jira (v8.3.4#803005)
