> 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....
