Description

flink-table depends on Apache Calcite which includes a JDBC Driver that prevents classloaders from being collected. This is a known issue with java.sqlDriverManager and can eventually cause OOME Permgen Taskmanager failures.

The current workaround is to not include flink-table in the fat job JAR. Instead the flink-table jar files should be added to the lib folder of the TaskManagers.
