> Key: FLINK-8887
> URL: https://issues.apache.org/jira/browse/FLINK-8887
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 1.5.0
> Reporter: Gary Yao
> Assignee: Till Rohrmann
> Priority: Blocker
> Labels: flip-6, pull-request-available
> Fix For: 1.5.0
>
>
> *Description*
> Calling {{RestClusterClient.getJobStatus}} or {{MiniClusterClient.getJobStatus}} can result in a {{FencingTokenException}}.
> *Analysis*
> {{Dispatcher.requestJobStatus}} first looks the {{JobManagerRunner}} up by job id. If a reference is found, {{requestJobStatus}} is called on the respective instance. If not, the {{ArchivedExecutionGraphStore}} is queried. However, between the lookup and the method call, the {{JobMaster}} of the respective job may have lost leadership already (job finished), and has set the fencing token to {{null}}.
> *Stacktrace*
> {noformat}
> Caused by: org.apache.flink.runtime.rpc.exceptions.FencingTokenException: Fencing token mismatch: Ignoring message LocalFencedMessage(null, LocalRpcInvocation(requestJobStatus(Time))) because the fencing token null did not match the expected fencing token b8423c75bc6838244b8c93c8bd4a4f51.
