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.
> Create Table to support multiple levels of delimiters

> Key: HIVE-365
> URL: https://issues.apache.org/jira/browse/HIVE-365
> Project: Hadoop Hive
> Issue Type: New Feature
> Reporter: Zheng Shao
>
> 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.
