Subject always insert overwrite, so how do we collect data?
Date Mon, 31 Jan 2011 19:56:32 GMT

I understand there is no way to delete data stored in a table. like a
`delete from table_name` in the hive language.
All this is fine, because all the query results are inserted into
another table, and the previous data in it is overwritten.

When we need to store data collectively in to a table, like add more
rows to it with each run, how do we do it?

Best Regards,
