The metaspace out-of-memory error has occurred. This can mean two things: either the job requires a larger size of JVM metaspace to load classes or there is a class loading leak. In the first case 'taskmanager.memory.jvm-metaspace.size' configuration option should be increased. If the error persists (usually in cluster after several job (re-)submissions) then there is probably a class loading leak which has to be investigated and fixed. The task executor has to be shutdown... MemoryAnalyzer??dump 700m 70??m ??
