             Summary: Incorrect handling of tables with custom delimiter when their data contain '|'
                 Key: TAJO-1339
                 URL: https://issues.apache.org/jira/browse/TAJO-1339
             Project: Tajo
          Issue Type: Bug
            Reporter: Keuntae Park


With the table data
{code}
1;a;1.1
2;a|b;2.4
3;b|c|d;3.2
{code}
and external table declaration
{code}
create external table delimiter (id int, name text, score float) using csv
with ('csvfile.delimiter'=';') location 'xxx';
{code}
, I got the following incorrect query result for 'query select name, score from delimiter'
{code}
name,score
-------------------------------
a,1.1
a,null
b,null
{code}

It looks like '|' in name column is recognized as delimiter.
As I inspect the code,
table meta information like 'csvfile.delimiter' is only valid on leaf scan operation and all the other operations (including making intermediate data and materialize query result) assumes that delimiter is DEFAULT_FIELD_DELIMITER, which is '|'.
Hence, if the plan has the process of making intermediate data, 
it handles '|' in the data as a delimiter even though it is not actually.
