> If users write wrong path at tajo-site.xml such as 'tajo.worker.tmpdir.locations', tajo can't execute queries. In this case, TajoWorker just remained 0 percent as follows: 
> {code:xml}
> tajo> create external table table1 (id int, name text, score float, type text) using csv with ('csvfile.delimiter'='|') location 'hdfs://service-cluster/user/tajo/warehouse/table1';
> OK
> tajo>
> tajo>
> tajo> select * from table1;
