--------------------------------------
[~sershe] Hi. Did you face this problem on CBO?
I'm working on [HIVE-12342|https://issues.apache.org/jira/browse/HIVE-12342],
and after setting {{hive.optimize.index.filter}} to true, I faced that my q
tests particularly {{TestTezPerfCliDriver}} have different outputs each launch.
{code:java}
-
Conds:RS_202._col0=RS_186._col0(Inner),Output:["_col1"]
+
Conds:RS_202._col0=RS_184._col0(Inner),Output:["_col1"]
<-Map 12 [SIMPLE_EDGE] vectorized
- PARTITION_ONLY_SHUFFLE [RS_186]
+ PARTITION_ONLY_SHUFFLE [RS_184]
PartitionCols:_col0
- Select Operator [SEL_185] (rows=4058
width=1119)
+ Select Operator [SEL_183] (rows=4058
width=1119)
Output:["_col0"]
- Filter Operator [FIL_184] (rows=4058
width=1119)
+ Filter Operator [FIL_182] (rows=4058
width=1119)
{code}
I think it is related to this JIRA. What do you think about it?
Thanks, Igor.
