>          Issue Type: Bug
>          Components: HiveServer2, Metastore

> When UDFs are used, we create a new classloader to add the UDF jar. Similar to what hadoop's
reflection utils does(HIVE-11408), datanucleus caches the classloaders (https://github.com/datanucleus/datanucleus-core/blob/3.2/src/java/org/datanucleus/NucleusContext.java#L161).
JDOPersistanceManager factory (1 per JVM) holds on to a NucleusContext reference (https://github.com/datanucleus/datanucleus-api-jdo/blob/3.2/src/java/org/datanucleus/api/jdo/JDOPersistenceManagerFactory.java#L115).
Until we call  NucleusContext#close, the classloader cache is not cleared. In case of UDFs
this can lead to permgen leak, as shown in the attached screenshot, where NucleusContext holds
on to several URLClassloader objects.
