Hey Nick, Hopefully PHOENIX-2599 works out for you, but it's entirely possible there's some other issues that crop up. My usage patterns are probably a bit unique, in that I generally do a few JDBC UPSERT SELECT aggregations from my "hot" tables to intermediate ones before Spark ever involved. That likely hides an entire class of bugs, like the kind PHOENIX-2599 fixes.
However, as you're likely aware, the Spark integration is a pretty thin wrapper over the regular MR integration, including Pig, so hopefully there's not too much in the way of unexplored territory there in terms of bulk loading and saving. Good luck! Josh On Sat, Jan 23, 2016 at 9:12 PM, Nick Dimiduk <ndimi...@apache.org> wrote: > That looks about right.
