> Stats reported multiple times during MR execution for UNION queries

> Key: HIVE-22501
> URL: https://issues.apache.org/jira/browse/HIVE-22501
> Project: Hive
> Issue Type: Bug
> Reporter: Daniel Voros
> Assignee: Daniel Voros
> Priority: Major
> Labels: mapreduce
> Attachments: HIVE-22501.1.patch
>
>
> Take the following example:
> {code}
> set hive.execution.engine=mr;
> create table tb(id string) stored as orc;
> insert into tb values('1');
> create table tb2 like tb stored as orc;
> insert into tb2 select * from tb union all select * from tb;
> {code}
> Last insert results in 2 records in the table, but
> {{TOTAL_TABLE_ROWS_WRITTEN}} statistic (and number of affected rows on the
> consolse) is 4.
> We seem to traverse the operator graph multiple times starting from every TS
> operator and increment the counters every time we hit the FS operator.
> UNION-ing the table 3 times results in 9 TOTAL_TABLE_ROWS_WRITTEN.
