to look at the new patch set (#2).
Change subject: IMPALA-10677: Set selectivity of Not-equal
......................................................................
IMPALA-10677: Set selectivity of Not-equal
Calculate binary predicate selectivity if one of the children is
a slotref and the other children are all constant.
eg. something like "col = 5", but not "2 * col = 10"
selectivity = 1 - 1/ndv
Testing:
Modify the function testNeSelectivity() of the
ExprCardinalityTest.java, change -1 to the correct value.
