Using hive 1.2.1.2.3 Connecting using JDBC, issuing the following query :
SELECT COUNT(*)
FROM nation n
INNER JOIN (customer c
INNER JOIN orders o ON c.c_custkey = o.o_custkey)
ON n.n_nationkey = c.c_nationkey;
Generates the NPE and stack below. Fields are integer data type
Does anyone know if this is a known issue and whether it's fixed someplace
?
Thanks,
Dave
