You are right; thanks. No stringComparator needed.
src/main/java/org/apache/hadoop/hbase/HServerLoad.java
<https://reviews.apache.org/r/2029/#comment5426>
I think there's a need for a data member here because HServerLoad needs an
initial set of regionserver-level coprocessors supplied to it when it is
constructed (this is the last parameter "final Set<String> coprocessors" that
we have added to the HServerLoad constructor).
Then, when getCoprocessors() is called, we take the union of those
regionserver-level coprocessors with all of the currently-loaded region-level
coprocessors.
I am creating a local returnValue that holds this set union, in
getCoprocessors(), to make this more clear hopefully, and adding documentation
to that effect.

Removed stringComparator since it's not needed for TreeSet<String> - thanks.

Good point, thank you.

Thanks, good idea.

Mingjie recommends moving to TestClassLoading.java - sounds good to me.
