jeff little commented on HIVE-5245:
-----------------------------------
Hi, Yin Huai. What is going on next step "Can you try the trunk?"
I deem that the middle join results of join operator may not be saved and not
be written to the temp HDFS. In other words, it may be failure, like 'Stage-7
is filtered out by condition resolver'.
The other problem that we encountered recently is like below:
hive (test)> select a.* from test_01 a
> join (select b.id from test_02 b
> join test_03 c
> on (b.id =c.id)) d
> on (a.id=d.id);

Note： the table of test_01, test_02 and test_03 have data, and have the same
values of id, but we can't get results. Inversely, it returns nothing. The
problem may also be caused by “Stage-12 is filtered out by condition resolver”.
