Andrew Purtell updated HBASE-9941:
----------------------------------
Attachment: 9941.patch
Something like this as a start maybe? Passes all tests locally. I'm not sure if
there is a significant performance impact yet. I suspect not, but should check
with a microbenchmark.
> The context ClassLoader isn't set while calling into a coprocessor

>
> Whenever one of the methods of a coprocessor is invoked, the context
> {{ClassLoader}} isn't set to be the {{CoprocessorClassLoader}}. It's only
> set properly when calling the coprocessor's {{start}} method. This means
> that if the coprocessor code attempts to load classes using the context
> {{ClassLoader}}, it will fail to find the classes it's looking for.
