Igor Kryvenko commented on HIVE-12342:
--------------------------------------
[~djaiswal] Hi. I did it because each launching of Tez tests produced a
different output in semijoin branch.
E.g.
{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]
{code}
As I understand it is caused in the connection phase of edges in
{{TezCompiler}} when we loop by {{rsToRuntimeValuesInfo}}.
