      When get request was issued, testHBase3583,,1395732494518.0cf2d2dd97dfedc860c5aa76c193e3e4. hasn't completed opening.
      This led to region server abort because of the following assertion in SimpleRegionObserver#postGetClosestRowBefore:

          assertNotNull(result);
      

      TestRegionObserverInterface#testHBase3583 should wait for all regions to be assigned
