      Description

      Saw a failure during some testing with region_mover.rb

      NativeException: java.lang.NullPointerException: null
              __ensure__ at /usr/hdp/current/hbase-master/bin/region_mover.rb:110
        isSuccessfulScan at /usr/hdp/current/hbase-master/bin/region_mover.rb:109
        isSuccessfulScan at /usr/hdp/current/hbase-master/bin/region_mover.rb:104
           unloadRegions at /usr/hdp/current/hbase-master/bin/region_mover.rb:328
      

      To try to get a real stacktrace, I wrote a simple test. Turns out, it was really simple to just produce the NPE within ClientScanner.

      java.lang.NullPointerException: null
      	at org.apache.hadoop.hbase.client.ClientScanner.getResultsToAddToCache(ClientScanner.java:576)
      	at org.apache.hadoop.hbase.client.ClientScanner.loadCache(ClientScanner.java:492)
      	at org.apache.hadoop.hbase.client.ClientScanner.next(ClientScanner.java:364)
      

      Patch with fix and test incoming.
