Introduced in HIVE-5871, MultiDelimitSerDe allows user to specify multiple-character string as the field delimiter when creating a table.
Hive 0.14.0 and later.
Hive QL Syntax
You can use MultiDelimitSerDe in a create table statement like this:
where field.delim is the field delimiter, collection.delim and mapkey.delim is the delimiter for collection items and key value pairs, respectively.
HIVE-20619 moved MultiDelimitSerDe to hive.serde2 in release 4.0.0, so user won't have to install hive-contrib JAR into the HiveServer2 auxiliary directory.
- Among the delimiters, field.delim is mandatory and can be of multiple characters, while collection.delim and mapkey.delim is optional and only support single character.
- Nested complex type is not supported, e.g. an Array<Array>.
- To use MultiDelimitSerDe prior to Hive release 4.0.0, you have to add the hive-contrib jar to the class path, e.g. with the add jar command.
