Gabriel Reid commented on PHOENIX-2716:
---------------------------------------
[~jamestaylor] FWIW, I ran a test of this on a single-node cluster with an
import of several million rows, with 4.5, 4.6, and the current master (i.e.
just after the revert of PHOENIX-1973), and verified that performance of master
is now pretty much in line with the performance in 4.5 (and that the work is
appropriately being distributed over multiple reducers). I also verified that
4.6 was indeed broken (I believe [~sergey.soldatov] confirmed this as well on
the mailing list).
It would be great if someone could run this on a distributed env, but even
failing that, I think this looks good for a new RC.
