------------------------------------

What’s in the pull requests looks ok though. I was a bit confused by the 
attached patch.

> Currently when the AtlasPluginClassLoader is deactivated it sets the current 
> threads class loader to class loader that was active when the class was 
> instantiated. In applications like Hive where a single thread may be shared 
> among multiple sessions each with its own class loader this is breaking class 
> loading for UDFs. The deactivate method should set the current threads class 
> loader back to the class loader that was set when activate was called.
