mahesh kumar behera updated HIVE-24013:
---------------------------------------
Description: The current anti join conversion is done before join
re-ordering rule. As Anti join is not handled in join re-ordering, it is better
to move the anti join conversion after join reordering is done. (was: The
current anti join conversion does not check for null filters on right side of
join if it's within OR conditions. Only those filters separated by AND
conditions are supported. For example queries like "select t1.fld from tbl1 t1
left join tbl2 t2 on t1.fld = t2.fld where t2.fld is null or t2.fld1 is null"
are not converted to anti join. )
