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}}.
