Pawel Szczur commented on BEAM-315: ----------------------------------- As far as I understand the issue there are 3 places it may originate from: 1. windowing (all items should end up in one global pane) 2. shuffle (is windowing considered during shuffle?) 3. sorting items in a given shard (is sorting considered?) Am I correct? > Flink Runner compares keys unencoded which may produce incorrect results > ------------------------------------------------------------------------ > > Key: BEAM-315 > URL: https://issues.apache.org/jira/browse/BEAM-315 > Project: Beam > Issue Type: Bug > Components: runner-flink > Affects Versions: 0.1.0-incubating > Reporter: Pawel Szczur > Assignee: Aljoscha Krettek > Attachments: CoGroupPipelineStringKey.java > > > Same keys are processed multiple times. > A repo to reproduce the bug: > https://github.com/orian/cogroup-wrong-grouping > Discussion: > http://mail-archives.apache.org/mod_mbox/incubator-beam-user/201605.mbox/%3CCAB2uKkG2xHsWpLFUkYnt8eEzdxU%3DB_nu6crTwVi-ZuUpugxkPQ%40mail.gmail.com%3E > Notice: I haven't tested other runners (didn't manage to configure Spark). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
