> *Problem*
> HADOOP-12829 ticket was implemented recently. It introduces special worker thread which monitors file system statistics. When several {{HadoopClassLoader}}s are created, one thread start for each of them. As this thread is never stopped, classloaders are never unloaded -> leak.
> *Solution*
> We need to investigate on how to hack into this process and prevent start of these thread. May be we will have to implement our own threads serving the same purpose.
