Subject [jira] Commented: (HIVE-365) Create Table to support multiple levels of delimiters
Date Fri, 11 Jun 2010 06:20:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12877731#action_12877731
] 

mangaiappan commented on HIVE-365:
----------------------------------

Multiple separators works with only control characters , and does not works with normal characters
.

CREATE TABLE nested(array_of_arrays ARRAY < ARRAY <INT>>, map_of_maps MAP <
STRING, MAP < INT, INT> > )
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '@''#''$''%''&'

Now , except for @ ,other separators are not recognized as separators.

> From HIVE-337, the SerDe layer now supports multiple-levels of delimiters, for the purpose
of supporting nested map/array/struct.
> Array(the same as List) and struct consume a single level of separator, and Map consumes
2 levels.
> DDL (Create Table) needs to allow users to specify multiple levels of delimiters in order
to take the advantage of this new feature.
