Rui Li commented on HIVE-17549:
-------------------------------

Thanks for the explanations [~txhsj]. It seems row container doesn't make 
efforts to secure the rows written to disk. That's why I'm not sure whether we 
need a stronger digest for the file name. [~taoli-hwx] what's your opinions 
about this?
