> The "org.apache.hadoop.fs.FileSystem$Statistics$StatisticsDataReferenceCleaner" daemon thread was created by FileSystem. 
> This is fine if the thread's context class loader is the system class loader, but it's bad if the context class loader is a custom class loader. The reference held by this daemon thread means that the class loader can never become eligible for GC.
