Hi, We had the same metaspace problem, it was solved by adding the jar file to the /lib path of every task manager, as explained here https://ci.apache.org/projects/flink/flink-docs-release-1.4/monitoring/debugging_classloading.html#avoiding-dynamic-classloading. As well we added these java options: "-XX:CompressedClassSpaceSize=100M -XX:MaxMetaspaceSize=300M -XX:MetaspaceSize=200M "
