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

+1 for 0.98

Out of curiosity, have you tried this with Apache Phoenix? 

As part of RC validation for 0.98 I will, so will back this change out if that presents a
problem.

> CoprocessorClassLoader is used to load classes from the coprocessor jar.
> Certain classes are exempt from being loaded by this ClassLoader, which means they will
be ignored in the coprocessor jar, but loaded from parent classpath instead.
> One problem is that we categorically exempt "org.apache.hadoop".
> But it happens that Hive packages start with "org.apache.hadoop".
> There is no reason to exclude hive classes from theCoprocessorClassLoader.
> HBase does not even include Hive jars.
