Subject RE: How to update and delete a row in hive
Date Tue, 11 Sep 2012 13:13:02 GMT
Hive does not support row-level (or field-level) updates. It is designed as a WORM (write once
read many) data warehouse. 

You can of course code your own row updates by reading an entire Hive file, modifying a row,
then writing the file back to Hive.

work around for that?
