> Key: FLINK-12183
> URL: https://issues.apache.org/jira/browse/FLINK-12183
> Project: Flink
> Issue Type: Bug
> Components: Runtime / REST
> Affects Versions: 1.6.4, 1.7.2, 1.8.0
> Reporter: Yumeng Zhang
> Priority: Major
> Labels: pull-request-available
>
> The per-job Yarn cluster doesn't releases resources after cancel a running
> job if the job restarted many times, like 1000 times, in a short time.
> The bug is in archiveExecutionGraph() phase before executing
> removeJobAndRegisterTerminationFuture(). The CompletableFuture thread will
> exit unexpectedly with NullPointerException in archiveExecutionGraph() phase.
> It's hard to find that because here it only catches IOException. In
> SubtaskExecutionAttemptDetailsHandler and
> SubtaskExecutionAttemptAccumulatorsHandler, when calling
> archiveJsonWithPath() method, it will construct some json information about
> prior execution attempts but the index is from 0 which might be dropped index
> for the for loop. In default, it will return null when trying to get the
> prior execution attempt (AccessExecution attempt =
> subtask.getPriorExecutionAttempt(x)).
