icexelloss commented on issue #1341: [WIP] ARROW-1710: [Java] Remove 
Non-Nullable Vectors
URL: https://github.com/apache/arrow/pull/1341#issuecomment-346386518
 
 
   @BryanCutler High level looks good to me. Two major comments:
   * Do we want to port the missing function (`getNullCount()` and 
`setRangeToOne`) to the new bit vector?
   * Can we remove `NonNullableMapVector` altogether? (git rid of the 
`MapVector extends NonNullableMapVector` inherence and roll them into a single 
class )
   
   Happy thanksgiving!
