forrest_feng commented on FLINK-21311: -------------------------------------- I tried ,but it's not the way to solve the problem, I want to know the reason why it is run ok in 1.11 but gets wrong in 1.12 with the same code . You'd better run the demo in your computer in different Flink edition , my intuition tells me it`s a big bug in FLINK 1.12 > flink1.12 cep does not execute pattern but flink1.10 is ok > ------------------------------------------------------------ > > Key: FLINK-21311 > URL: https://issues.apache.org/jira/browse/FLINK-21311 > Project: Flink > Issue Type: Bug > Components: Library / CEP > Affects Versions: 1.12.0 > Reporter: forrest_feng > Priority: Major > Attachments: CEPTest.java > > > I am trying to test CEP demo according to Official website example, I found > no data enter the pattern to print log , finally, I replace my FLINK > version from 1.12 to 1.10, Flink 1.10 is ok, may be this is bug of Flink > 1.12 -- This message was sent by Atlassian Jira (v8.3.4#803005)
