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.

Hi All,


I am trying to change GC settings of Taskmanager. I am using flink 1.18 and 
Java 8. 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
