------------------------------------
Summary: Configure Metaspace size by default
Key: FLINK-10317
URL: https://issues.apache.org/jira/browse/FLINK-10317
Project: Flink
Issue Type: Bug
Components: Startup Shell Scripts
Affects Versions: 1.5.3
Reporter: Stephan Ewen
We should set the size of the JVM Metaspace to a sane default, like
{{-XX:MaxMetaspaceSize=256m}}.
If not set, the JVM offheap memory will grow indefinitely with repeated
classloading and Jitting, eventually exceeding allowed memory on docker/yarn or
similar setups.
It is hard to come up with a good default, however, I believe the error
messages one gets when metaspace is too small are easy to understand (and easy
to take action), while it is very hard to figure out why the memory footprint
keeps growing steadily and infinitely.
