jiatao.tao commented on KYLIN-3635: ----------------------------------- Hi Shaofeng, do you think we should provide a stronger constraint about this? I've tried to make method reset() abstract so that the subclasses have to implement this, but I found most of the implementation is still empty. What's your opinion about this? > Percentile calculation on Spark engine is wrong > ----------------------------------------------- > > Key: KYLIN-3635 > URL: https://issues.apache.org/jira/browse/KYLIN-3635 > Project: Kylin > Issue Type: Bug > Components: Spark Engine > Affects Versions: v2.3.0, v2.3.1, v2.4.0, v2.3.2, v2.4.1, v2.5.0 > Reporter: Shaofeng SHI > Assignee: Shaofeng SHI > Priority: Major > Fix For: v2.4.2, v2.5.1 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
