-----------------------------------------
[~osayankin] I've removed fix version yesterday because that field should not be filled out until the patch is submitted...this is documented in the hive wiki, please search for fix version in https://cwiki.apache.org/confluence/display/Hive/HowToContribute
Could you please answer Ashutosh's question?
