Hi, Banu. Could you check whether the "Configuration" icon under the "Task Managers" and "Job Manager" buttons on the left side of the Flink-UI
shows that the currently effective flink conf includes these JVM changes? I suspect that you are using a session cluster mode, where changes to the yaml file only affect the job, not the cluster. -- Best!

Jave 8 uses parallel GC by default. I need to change it to use G1GC. In flink-conf.yaml, I passed the property ( refer attached image line no. 357). But it is not reflecting. What am I doing wrong? Thanks Banu
