Wencong Liu commented on FLINK-30507: ------------------------------------- Hello [~renqs]. For this failed IT case, I found that the main reason is ZookeeperServer startup timed out. ZookeeperServer uses the minSessionTimeout value as the actual timeout parameter by default, and the default value of minSessionTimeout is 6s. Currently, only maxSessionTimeout = 60s is configured in the startup configuration. Since it's larger than the default value of 6s, this configuration does not take effect. !image-2022-12-29-15-52-17-508.png! !image-2022-12-29-15-48-55-564.png! !image-2022-12-29-15-51-12-230.png! Therefore, minSessionTimeout can be set to avoid the slow startup of ZookeeperServer when resources are tight. I tend to set minSessionTimeout to 12s. Do you think this change is reasonable? > EventTimeWindowCheckpointingITCase.testTumblingTimeWindowWithKVStateMinMaxParallelism > could not be initialized > -------------------------------------------------------------------------------------------------------------- > > Key: FLINK-30507 > URL: https://issues.apache.org/jira/browse/FLINK-30507 > Project: Flink > Issue Type: Bug > Components: Tests > Affects Versions: 1.17.0 > Reporter: Qingsheng Ren > Priority: Major > Attachments: image-2022-12-29-15-48-55-564.png, > image-2022-12-29-15-51-12-230.png, image-2022-12-29-15-52-17-508.png > > > https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=44245&view=logs&j=4d4a0d10-fca2-5507-8eed-c07f0bdf4887&t=7b25afdf-cc6c-566f-5459-359dc2585798&l=12367 -- This message was sent by Atlassian Jira (v8.20.10#820010)
