> As titled; Received reporting that percentile result is wrong when using
> Spark engine. Checked the code and found the object was reused and not reset,
> the problem won't happen on normal MR as it would be serialized before next
> call, but would be a problem on Spark, as the object was cached in-memory and
> be serialized later.
