Billie Rinaldi commented on HTRACE-6:
-------------------------------------

That's a good question, I'm having a bit of trouble tracking down why exactly 
Accumulo is comparing them.  My rough understanding is that the TraceRunnables 
are placed in a PriorityQueue, and it seems like the compareTo function is just 
deferring to the Runnable, if that is also Comparable.  I'll try to look into 
it some more, and see if Accumulo can use a Comparator instead.

> Make TraceRunnable implement Comparable

> Comparable<TraceRunnable>.
