Expected number of rows: 1
Actual number of rows from Drill: 1
Number of matching rows: 0
Number of rows missing: 1
Number of rows unexpected: 1
These rows are not expected (first 10):
8769
These rows are missing (first 10):
8773 (1 time(s))
Likewise for
/root/open-source-drill-test/testing/framework/resources/drill-smoke/tpch-smoke-passing/testcases/join02-merge.q
:
select count(*)
from (select c.c_custkey
from customer c, orders o
where c.c_custkey = o.o_custkey) as foo
These rows are not expected (first 10):
14990
These rows are missing (first 10):
15000 (1 time(s))
Note that it makes no difference whether planner.enable_broadcast_join is
turned on or off.
