> OrderByIT.testOrderByReverseOptimizationWithNUllsLastBug3491 is the only test failing on master (i.e. HBase 1.4). It's getting into an infinite loop when a reverse scan is done for the DistinctPrefixFilter. It'd be nice to fix this so we can do a release for HBase 1.4. At a minimum, we could disable DistinctPrefixFilter when a reverse scan is being done (for HBase 1.4 only).
