Example 37 with PersistenceManagerFactory

use of javax.jdo.PersistenceManagerFactory in project hive by apache.

the class ObjectStore method unCacheDataNucleusClassLoaders.

/**
 * Removed cached classloaders from DataNucleus
 * DataNucleus caches classloaders in NucleusContext.
 * In UDFs, this can result in classloaders not getting GCed resulting in PermGen leaks.
 * This is particularly an issue when using embedded metastore with HiveServer2,
 * since the current classloader gets modified with each new add jar,
 * becoming the classloader for downstream classes, which DataNucleus ends up using.
 * The NucleusContext cache gets freed up only on calling a close on it.
 * We're not closing NucleusContext since it does a bunch of other things which we don't want.
 * We're not clearing the cache HashMap by calling HashMap#clear to avoid concurrency issues.
