Chao updated HIVE-9113:
-----------------------
Description:
Run explain on the following query:
{noformat}
select p.p_partkey, li.l_suppkey
from (select distinct l_partkey as p_partkey from lineitem) p join lineitem li
on p.p_partkey = li.l_partkey
where li.l_linenumber = 1 and
li.l_orderkey in (select l_orderkey where l_linenumber = li.l_linenumber)
;
{noformat}
gave me NPE:

Is this query invalid? If so, it should at least give some explanations, not
