Shivaram Venkataraman commented on SPARK-9865:
----------------------------------------------
So we sample 10% in a DataFrame with 3 rows and expect to get less than 3 rows.
I guess there is a very small chance that you still get back 3 rows.
One fix for this might be to just sample 1% ? [~davies] Do you have any other
fix in mind ?
