Description

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:

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'
