   ### Version
   
   0.13 or later
   
   ### What's Wrong?
   
   When using spark load, bitmap count may be incorrect in a high cardinality scenario.
   
   
   ### What You Expected?
   
   Bitmap column  count is correct.
   
   ### How to Reproduce?
   
   This bug is triggered when the roaring bitmap exceeds 32 bits. 
   First, a high cardinality bitmap column more than `2^32` should be built. 
   Then, load data by spark load.
   Last, select the count distinct value and checked with the original data.
