Sergey Shelukhin updated HIVE-16289:
------------------------------------
    Attachment: HIVE-16289.01.patch

Rebased the patch. I see new parameters were added so perhaps the hint could be 
changed to be in a better format, like e.g. 
table_name=min,max,factor;table_name2;table_name3=... etc.
Anyway let me know first if this even makes sense.

> For now hints will only impact bloom filter size if semijoin is enabled.
> In a follow-up, after some cost-based semi-join decision logic is added, they 
> may also influence it.
