    Description

      In hive ds_hll_estimate_bounds() gives back an array of doubles.

      An example for a sketch created from a table which contains only a single value:

      (select ds_hll_estimate_bounds(ds_hll_sketch(i)) from t;)
      +-------------------------------+
      |              _c0              |
      +-------------------------------+
      | [1.0,1.0,1.0000998634873453]  |
      +-------------------------------+
      

      The values of the array is probably a lower bound, an estimate and an upper bound of the sketch.
