   > 1, pyspark and scala api only accept string `*str` / `string*`
   
   @zhengruifeng can you elaborate? I tested the same code in PySpark and it works as well. 
   
   
   
   > 2, pyspark and scala api will check the schema, if the datatype is unexpected, it fails;
   
   What do you mean? 
   
   
   > 
   > 3, if the no input column, it will check the schema and select all the numeric columns.
   
   This is more missing functionality than this particular bug correct?
