Overall looks good to me!  Just wanted to clarify on one small logging question.

Ah, that's interesting.  Where does KuduContext get the stats about the number 
of actually deleted rows when it issues DELETE_IGNORE operations?  Does the 
server side report to the client about that stat?  It would be great if you add 
a comment clarifying on this, commenting about what's reported at the 
log.info() operator at line 347.

Thank you very much for adding this new scenario!
