> Hiveserver2 instances where crashing every 3-4 days and observed HS2 in on
> unresponsive state. Also, observed that the FGC collection happening regularly
> From JXray report it is seen that pmCache(List of JDOPersistenceManager
> objects) is occupying 84% of the heap and there are around 16,000 references
> of UDFClassLoader.
