Description
It'd be great to have an option to TRUNCATE tables before exporting data to them.
There were a couple of mailing list posts about this feature already[1].
Sometimes the data has to be replaced completely and having the option of Sqoop taking care of clearing the data first would be convenient. Currently we need to run a custom java action first that does the truncating.
