Ashutosh Chauhan updated HIVE-1237:
-----------------------------------
Attachment: hive-1237_1.patch
I think for coalesce it makes sense to have atleast two arguments. It returns
first non-null of its argument. If there is zero argument there is nothing to
return and if there is one argument it has to return that whether its null or
not. I updated the patch to throw exception if there are less then two
arguments.
