mahesh kumar behera updated HIVE-23904:
---------------------------------------
Description:
[TestMapJoinOperator.java|https://github.com/apache/hive/pull/1147/files/ee4390223caf1816ba6c07c1245876dc3c99d1e9#diff-a96ed41dcf0566f31b90b5ac75fbf20b]
should be updated to add test cases related to anti join. (was: In case of
anti join, bloom filter can be created on left side also ("IN (keylist right
table)").But the filter should be "not-in" ("NOT IN (keylist right table)") as
we want to select the records from left side which are not present in the right
side. But it may cause wrong result as bloom filter may have false positive and
thus simply adding not is not correct, special handling is required for "NOT
IN".
