> Percentile calculation on Spark engine is wrong
> -----------------------------------------------

> Key: KYLIN-3635
> URL: https://issues.apache.org/jira/browse/KYLIN-3635
> Project: Kylin
> Issue Type: Bug
> Affects Versions: v2.3.0, v2.3.1, v2.4.0, v2.3.2, v2.4.1, v2.5.0
> Reporter: Shaofeng SHI
> Priority: Major
>
> 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.
