> Seems a split operation which we expect to success is started before we
> finishing a merge and cause an infinite sleep loop.
> I guess the problem is here
> {code:title=TestNamespaceAuditor.java}
> // merge the two regions
> admin.mergeRegions(hris.get(0).getEncodedNameAsBytes(),
> hris.get(1).getEncodedNameAsBytes(), false);
>
> while (admin.getTableRegions(tableTwo).size() == initialRegions) {
> Thread.sleep(100);
> }
> {code}
> I guess that during a merge, we can get more region count than before because
> we first online the new region and then offline the two old regions.
> So change it to admin.getTableRegions(tableTwo).size() != initialRegions - 1
> may work.
> And we can modify the while loop to use Waiter.waitFor which can provide more
> useful information when test failed.
