Zhu Zhu created FLINK-12131: ------------------------------- Summary: Resetting ExecutionVertex in region failover may cause inconsistency of IntermediateResult status Key: FLINK-12131 URL: https://issues.apache.org/jira/browse/FLINK-12131 Project: Flink Issue Type: Bug Components: Runtime / Coordination Affects Versions: 1.9.0 Reporter: Zhu Zhu Assignee: Zhu Zhu
Currently the *IntermediateResult* status is only reset when its producer *ExecutionJobVertex* is reset. When region failover strategy is enabled, the failed region vertices are reset through *ExecutionVertex.resetForNewExecution()*. The *numberOfRunningProducers* counter in IntermediateResult, however, is not properly adjusted in this case. So if a FINISHED vertex is restarted and finishes again, the counter may drop below 0. Besides, the consumable property of the partition is not reset as well. This may lead to incorrect input state check result for lazy scheduling. I'd propose to invoke *IntermediateResultPartition.resetForNewExecution()* in *ExecutionVertex.resetForNewExecution()* and reset the *numberOfRunningProducers* counter and *IntermediateResultPartition* there. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
