[jira] [Commented] (HIVE-14867) "serialization.last.column.takes.rest" does not work for MultiDelimitSerDe

["Niklaus Xiao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-14867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15535660#comment-15535660 ] 

Niklaus Xiao commented on HIVE-14867:
-------------------------------------

{{LazySimpleSerDe}} works as expected:
{code}
create table t__2(a string, b string) row format delimited fields terminated by ',' stored as textfile;
{code}

load data into table t__2:
{code}
1,Lily,HW,abc
2,Lucy,LX,asdf
3,Lilei,XX,ss
{code}

select from t_2:
{code}
select * from t__2;
+---------+---------+--+
| t__2.a  | t__2.b  |
+---------+---------+--+
| 1       | Lily    |
| 2       | Lucy    |
| 3       | Lilei   |
+---------+---------+--+
3 rows selected (0.382 seconds)
{code}

> Create table with MultiDelimitSerde:

> CREATE TABLE foo (a string, b string) ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.MultiDelimitSerDe' WITH SERDEPROPERTIES ("field.delim"="|@|","collection.delim"=":","mapkey.delim"="@") stored as textfile;

> 3|@|Lilei|@|XX|@|3434
> {code}
> select data from this table:

^AXX
^A3434  |

> You can see the last column takes all the data, and replace the delimiter to default ^A.
> lastColumnTakesRestString should be false by default: 
> {code}
>     String lastColumnTakesRestString = tbl
>         .getProperty(serdeConstants.SERIALIZATION_LAST_COLUMN_TAKES_REST);
>     lastColumnTakesRest = (lastColumnTakesRestString != null && lastColumnTakesRestString
>         .equalsIgnoreCase("true"));
> {code}
