Jason Dere created HIVE-12563:
---------------------------------
Summary: NullPointerException with 3-way Tez merge join
Key: HIVE-12563
URL: https://issues.apache.org/jira/browse/HIVE-12563
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 1.2.0
Reporter: Jason Dere
Issue occurs in Tez merge joins with 3 way join (A join B join C), where A is
the big table, and A and C end up having 0 rows after table filters.
Was able to repro this issue with using the sample tables in the Hive unit
tests:
{noformat}
select
a.key, b.value, c.value
from
src a,
src1 b,
src c
where
a.key = b.key and a.key = c.key
and a.value > 'wal_6789'
and c.value > 'wal_6789'
