      Description

      2017-03-07 12:54:39,459 [master.Master] ERROR: Error balancing tablets, will wait for 1 (seconds) and then retry
      java.lang.NullPointerException

      This is spewed across the Master log. Apparently something changed in the Balancer API or implementation since 1.7.1 (when I fixed this test in ACCUMULO-3356)?
