Review request for Tajo.
Bugs: TAJO-848
https://issues.apache.org/jira/browse/TAJO-848
Repository: tajo
Description
-------
Currently, user can insert data even if there is small columns compare to
target columns as follows:
create table table1 (id int, name text, score float, type text) using csv with
('csvfile.delimiter'='|') ;
create table table3 (id int, name text, score float, type text) using csv with
('csvfile.delimiter'='|') ;
create table table4 (id int, name text, score float, type text) using csv with
('csvfile.delimiter'='|') partition by column(part text);
default> insert overwrite into table3 select id, name from table1;
Progress: 0%, response time: 0.544 sec
Progress: 100%, response time: 1.158 sec
(5 rows, 1.158 sec, 60 B inserted)
default> insert overwrite into table4 select id, name from table1;
Progress: 100%, response time: 0.468 sec
(5 rows, 0.468 sec, 65 B inserted)
As above, tajo can run a query for inserting data. But in partitioned table,
tajo made null value for partition column as follows:
hdfs dfs -ls /tajo/warehouse/default/table4
Found 1 items
drwxr-xr-x - blrunner supergroup 0 2014-05-26 16:27
/tajo/warehouse/default/table4/part=
Thus we need to make a syntax exception for blocking null partition value.
