> A mismatch in the code on the cluster revealed an infinite loop.  The .META. scanner
is doing a socket timeout trying to contact a borked region server (The borked server was
having trouble contacting hdfs because of of code version mismatch -- it was sort-of-working).
 We retry the timeout up to the retry limit but then rather than try and redeploy the unreachable
.META. we just drop back into scanning at the old location.... I'll attach a log that illustrates
the goings-on.
> I think this likely a trivial issue since it shouldn't really ever happen....
