This was due to more than one column being visible:
{code}
// check: should always see exactly one column
Get g = new Get(row);
Result r = region.get(g, null);
if (r.size() != 1) {
LOG.debug(r);
failures.incrementAndGet();
fail();

> I've seen many unspecific test failures recently that cannot be reproduced
> locally even when running these test is a loop for a very long time.
> Many of these test one way or the other make assumption w.r.t. wall clock
> time. While I cannot fix that, an option to increase some of these timeout a
> bit.
> This issue is to remind me to do that.
