ASF GitHub Bot updated FLINK-21178: ----------------------------------- Labels: pull-request-available (was: ) > Task failure will not trigger master hook's reset() > --------------------------------------------------- > > Key: FLINK-21178 > URL: https://issues.apache.org/jira/browse/FLINK-21178 > Project: Flink > Issue Type: Bug > Components: Runtime / Checkpointing > Affects Versions: 1.11.3, 1.12.0 > Reporter: Brian Zhou > Priority: Major > Labels: pull-request-available > > In Pravega Flink connector integration with Flink 1.12, we found an issue > with our no-checkpoint recovery test case [1]. > We expect the recovery will call the ReaderCheckpointHook::reset() function > which was the behaviour before 1.12. However FLINK-20222 changes the logic, > the reset() call will only be called along with a global recovery. This > causes Pravega source data loss when failure happens before the first > checkpoint. > [1] > [https://github.com/crazyzhou/flink-connectors/blob/da9f76d04404071471ebd86bf6889b307c9122ff/src/test/java/io/pravega/connectors/flink/FlinkPravegaReaderRGStateITCase.java#L78] -- This message was sent by Atlassian Jira (v8.3.4#803005)
