-| Key     | Default      | Type     | Required | Description                   
 |
-|:--------|:-------------|:---------|:---------|:-------------------------------|
-| weights | `[1.0, 1.0]` | Double[] | no       | The weights of data 
splitting. |

splitting.

+| seed    | `null`       | Long     | no       | The random seed. This 
parameter works only when the parallelism is consistent and each worker read 
the same data in the same order.  |

Review Comment:
   How about update the descriptions as:
   '''
   The random seed. This parameter guarantees reproduciable output only when 
the paralleism is unchanged and each worker reads the same data in the same 
order.
