The query profile for completed queries contain 2 entries for operatorType=11 (UNORDERED_RECEIVER) for the same major and minor fragment. Here is an example:
0: jdbc:drill:schema=dfs.hbase> select t3.majorId, t3.minfid,t3.oProfile.operatorType operator_type from (select t2.majorFragmentId majorId,t2.minorFragmentProfile.minorFragmentId minfid,flatten(t2.minorFragmentProfile.operatorProfile) oProfile from (select t1.col.majorFragmentId majorFragmentId, flatten(t1.col.minorFragmentProfile) minorFragmentProfile from (select flatten(t.fragmentprofile) col from `dfs.drillTestDir`.`/ui_profiles/query1.json`t) t1) t2) t3 where t3.majorId=2 and t3.oProfile.operatorType=11;
+------------+------------+---------------+
| majorId | minfid | operator_type |
+------------+------------+---------------+
| 2 | 0 | 11 |
| 2 | 0 | 11 |
| 2 | 2 | 11 |
| 2 | 2 | 11 |
| 2 | 1 | 11 |
| 2 | 1 | 11 |
+------------+------------+---------------+
The metrics for the first entry of each set is always 0.
