https://github.com/apache/spark/pull/17746
The motivation to have this one merged in Spark 2.2 is not only just for
#17715 but also because Breeze 0.13.x fixes many bugs in upstream. Since Spark
was tightened to 0.12, many users (including my company) have difficulty to
upgrade Breeze alone by themselves, which forces people to have a copy of
implements with fixes in the application code.
In the long term, because we only use Breeze's optimizer in Spark, we
should have our optimizer implementation in mllib-local to remove the heavy
external dependencies.
In retrospect, we started to work on the fix we want to have in upstream
too late, so we had the upstream to release the fixes right after the 2.2
branch was cut. We should definitely plan it earlier in the future.
