Ning Zhang commented on HIVE-734:
---------------------------------
I wasn't able to get an example in HIVE. I tried to insert NULL to a table by
modifying the test query input4_cb_delim.q (actually by only modifying the
input data to be
<value1>\002\012
\002<value2>\012
and run the query
select * from input4_cb where key is not null;
and both rows are returned. So either the NULL values are not inserted
correctly, or the evaluation is not correct about NULL.
