Subject [jira] Commented: (HIVE-136) SerDe should escape some special characters
Date Thu, 22 Jan 2009 23:21:59 GMT


Joydeep Sen Sarma commented on HIVE-136:

looks like in right direction. questions:

- i like the logic of escaping row/column/key/item separators. do we allow anything other
than newline to be row separator?

- for deserialization - shouldn't we only unescape what we might have escaped during serialization?
(so should not be unescaping octals and nulls for example)

'\n' or the column/item/key separator.
