Aljoscha Krettek commented on FLINK-5247: ----------------------------------------- I see. Thanks for looking into this! I actually have a fix for this (ignore allowedLateness for processing time) buried in this PR: https://github.com/apache/flink/pull/2572/files#diff-408a499e1a35840c52e29b7ccab866b1R525 (You can look at WindowOperator.cleanupTime()). I think it would be better to ignore setting an allowed lateness for processing time. But you're right that the checks should be fixed. > Setting allowedLateness to a non-zero value should throw exception for > processing-time windows > ---------------------------------------------------------------------------------------------- > > Key: FLINK-5247 > URL: https://issues.apache.org/jira/browse/FLINK-5247 > Project: Flink > Issue Type: Bug > Components: Streaming > Affects Versions: 1.1.0, 1.1.1, 1.1.2, 1.1.3 > Reporter: Rohit Agarwal > > Related to FLINK-3714 and FLINK-4239 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
