Hi, I'm looking for clarity on the future of the spark execution engine for pig. While I've noticed activity on the spark branch on the pig git repo, it hasn't been merged to trunk since the initial spork announcement. Besides, it's not clear if it will continue to be maintained and enhanced to exploit spark's capabilities to a greater extent (e.g. caching of RDD's etc). I also see very little (up to date) user documentation on the setup. I hence seek clarity on the future of the backend. Thanks.
