> ---------------------------------
>
> Key: FLINK-9268
> URL: https://issues.apache.org/jira/browse/FLINK-9268
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream, Runtime / State Backends
> Affects Versions: 1.4.2
> Reporter: Narayanan Arunachalam
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> The job has no sinks, one Kafka source, does a windowing based on session and
> uses processing time. The job fails with the error given below after running
> for few hours. The only way to recover from this error is to cancel the job
> and start a new one.
> Using S3 backend for externalized checkpoints.
> A representative job DAG:
> val streams = sEnv
> .addSource(makeKafkaSource(config))
> .map(makeEvent)
> .keyBy(_.get(EVENT_GROUP_ID))
> .window(ProcessingTimeSessionWindows.withGap(Time.seconds(60)))
> .trigger(PurgingTrigger.of(ProcessingTimeTrigger.create()))
> .apply(makeEventsList)
> .addSink(makeNoOpSink)
> A representative config:
> state.backend=rocksDB
> checkpoint.enabled=true
> external.checkpoint.enabled=true
> checkpoint.mode=AT_LEAST_ONCE
> checkpoint.interval=900000
> checkpoint.timeout=300000
> Error:
> TimerException\{java.lang.NegativeArraySizeException}
