Description

https://issues.apache.org/jira/browse/SPARK-27495 has imported a great feature to help adjust stage's level resource profile(abbv rp), we are observing some config is not as expected when multiple resource profile works.
When one stage assigned rp2 different with default rp, the `UnifiedMemoryManager` will still get old conf as the default rp, which will cause maxOffHeapMemory is still the old value!

protected[this] val maxOffHeapMemory = conf.get(MEMORY_OFFHEAP_SIZE)
