Sean Owen commented on SPARK-25578:
-----------------------------------
[~sadhen] I got this failure from {{QueryTest}} with Scala 2.12.7, after
removing what I believed was your workaround for this Scala issue:
{code:java}
== Results ==
!== Correct Answer - 1 == == Spark Answer - 1 ==
!struct<array(100, 100):array<int>> struct<percentile_approx(100.0,
array(0.9, 0.9), 10000):array<double>>
![WrappedArray(100, 100)] [WrappedArray(100.0, 100.0)]
(QueryTest.scala:163){code}
Is that something we expected to be fixed, or maybe I misunderstood?
It passes with 2.12.7, without undoing your change.
