I agree with Imran, we need to fix SPARK-23243 and any correctness issues for
that matter.

SPARK-23243: Shuffle+Repartition on an RDD could lead to incorrect answers
It turns out to be a very complicated issue, there is no consensus about what
is the right fix yet. Likely to miss it in Spark 2.4 because it's a
long-standing issue, not a regression.
This is a really serious data loss bug. Yes its very complex, but we
absolutely have to fix this, I really think it should be in 2.4.Has worked on
it stopped?
