Zhilong Hong edited comment on FLINK-22276 at 4/14/21, 10:39 AM: ----------------------------------------------------------------- I've gone through the log and got some assumptions. In the log we can see there are two failovers that happen within 30 milliseconds: * failover 1 includes {{shuffleRead&Write (1/2)}} * failover 2 includes {{shuffleRead&Write (1/2) + shuffleRead&Write (2/2)}} It seems that {{restartTasks}} of failover 2 runs first, resets the execution of {{shuffleRead&Write (1/2)}}. Then {{archiveFromFailureHandlingResult}} of failover 1 runs, finds that there's no failure cause in the new execution of {{shuffleRead&Write (1/2)}}. was (Author: thesharing): I've gone through the log and got some assumptions.
