Till Rohrmann created FLINK-4046: ------------------------------------ Summary: Failing a restarting job can get stuck in JobStatus.FAILING Key: FLINK-4046 URL: https://issues.apache.org/jira/browse/FLINK-4046 Project: Flink Issue Type: Bug Components: Distributed Runtime Affects Versions: 1.1.0 Reporter: Till Rohrmann Fix For: 1.1.0
When a job is in state {{RESTARTING}}, then it can happen that all of its {{ExecutionJobVertices}} are in a final state (if they have not been reset). When calling {{fail}} on this {{ExecutionGraph}} will transition the state to {{FAILING}} and call cancel on all {{ExecutionJobVertices}}. The job state {{FAILING}} can only be left iff all {{ExecutionJobVertices}} have reached a final state. The notification of this final state is only sent to the {{ExecutionGraph}} when all subtasks of an {{ExecutionJobVertex}} have transitioned to a final state. However, this won't happen because the {{ExeuctionJobVertices}} are already in a final state. The result is that a job can get stuck in the state {{FAILING}} if {{fail}} is called on a {{RESTARTING}} job. I propose to add a direct transition from {{RESTARTING}} to {{FAILED}} as it is the case for the {{cancel}} call (transition from {{RESTARTING}} to {{CANCELED}}). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
