> I found a bug which TajoCli prints unexpected results in union query.
> For the first, TajoCli prints wrong row numbers as follows:
> {code:xml}
> tajo> select id from table1 union all select id from table2;
> result:
> hdfs://localhost:9010/tmp/tajo-blrunner/staging/q_1391680780275_0004/RESULT,
> 5 rows (21 B)
> id
> -------------------------------
> 6
> 7
> 8
> 9
> 10
> 1
> 2
> 3
> 4
> 5
> {code}
> And if empty table located on last phase, it just prints zero as follows:
> {code:xml}
> tajo> select id from table1 union all select id from table3;
> result:
> hdfs://localhost:9010/tmp/tajo-blrunner/staging/q_1391680780275_0005/RESULT,
> 0 rows (10 B)
> id
> -------------------------------
> {code}
> For reference, I created test tables as follows:
> {code:xml}
> CREATE EXTERNAL TABLE table1 (id INT4, name TEXT, score FLOAT4, type TEXT)
> USING CSV WITH ('csvfile.delimiter'='|') LOCATION
> 'hdfs://localhost:9010/tajo/warehouse/table1';
> CREATE EXTERNAL TABLE table2 (id INT4, name TEXT, score FLOAT4, type TEXT)
> USING CSV WITH ('csvfile.delimiter'='|') LOCATION
> 'hdfs://localhost:9010/tajo/warehouse/table2';
> CREATE EXTERNAL TABLE table3 (id INT4, name TEXT, score FLOAT4, type TEXT)
> USING CSV WITH ('csvfile.delimiter'='|') LOCATION
> 'hdfs://localhost:9010/tajo/warehouse/table3';
> tajo> select * from table1;
> result:
> hdfs://localhost:9010/tmp/tajo-blrunner/staging/q_1391680780275_0001/RESULT,
> 5 rows (60 B)
> id, name, score, type
> -------------------------------
> 1, ooo, 1.1, a
> 2, ppp, 2.3, b
> 3, qqq, 3.4, c
> 4, rrr, 4.5, d
> 5, xxx, 5.6, e
> tajo> select * from table2;
> result:
> hdfs://localhost:9010/tmp/tajo-blrunner/staging/q_1391680780275_0002/RESULT,
> 5 rows (61 B)
> id, name, score, type

> 8, qqq, 3.4, c
> 9, rrr, 4.5, d
> 10, xxx, 5.6, e
