Andrew Purtell commented on HBASE-9941:
---------------------------------------
Also, FYI, the latest version of Caliper is 1.0-test-1, but it's built against
a more recent version of Guava than we have available. We need to use Caliper
0.5-rc1 or we will see linkage errors against Guava's Stopwatch class.
> 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.
