Gary Yao commented on FLINK-15781: ---------------------------------- I tested with an adapted version of {{DataSetAllroundTestProgram}} with a parallelism of 100 and load factor 100, 200, and 500. Furthermore, I tested ExecutionModes {{BATCH}} and {{PIPELINED}} with all aforementioned load factors. Flink was deployed on a YARN cluster hosted on AWS EMR with 25 m5.xlarge NodeManagers. The job finished reliably in all configurations. > Manual Smoke Test with Batch Job > -------------------------------- > > Key: FLINK-15781 > URL: https://issues.apache.org/jira/browse/FLINK-15781 > Project: Flink > Issue Type: Task > Affects Versions: 1.10.0 > Reporter: Gary Yao > Assignee: Gary Yao > Priority: Critical > > Try out a (larger) scale batch job with {{"jobmanager.scheduler: ng"}} > enabled in {{flink-conf.yaml}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
