Imran Rashid commented on SPARK-24285:
--------------------------------------
I ran into this on one of my prs so I tried to take a quick look, but didn't
get anywhere. I didn't see anything obviously wrong in the test output, and I
ran a few hundred times on my laptop and failed to reproduce. one thing which
might help is changing that assert slightly so we can actually see what the
{{results}} are when it fails:
{code}
val results = spark.read.table("noharness").collect().toSet
assert(Set(0, 1, 2, 3).map(Row(_)).subsetOf(results), results)
{code}
> Flaky test: ContinuousSuite.query without test harness
