> After catching the exception generated by the findNextCompactionAndExecute() task, HS2 appears to immediately rerun the task with no delay or backoff.  As a result there are ~3500 connection attempts from HS2 to HMS over just a 5 second period in the HS2 log
> The compactor.Worker should wait between failed attempts and maybe do an exponential backoff.
