Dmitriy V. Ryaboy commented on PIG-259:
---------------------------------------
Yeah I think it makes more sense on that level.
I think it's worth our while to add it to PigStorage and any other built-in
engines though.
Otherwise it's not clear what the overwrite keyword means. If it's HBase, does
it mean drop the table and overwrite? Or delete old values when there is an old
confilct? Does that mean we don't delete them otherwise? What about appends?
This request made more sense when Pig maintained strong control over file
creation and such, but now that it's pushed into IOFormats, I think it's ok to
push this functionality there as well.
It's just a lot of stuff I think we don't want to be in the business of
creating interfaces for. Different storage engines have different options for
what they can and can't do.
