> 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.
