> Flacon's instance retry service may hang because of an issue in InMemoryQueue
> -----------------------------------------------------------------------------
>
> Key: FALCON-46
> URL: https://issues.apache.org/jira/browse/FALCON-46
> Project: Falcon
> Issue Type: Bug
> Components: rerun
> Affects Versions: 0.3
> Environment: Oozie 3.2, CDH3U5
> Reporter: Shaik Idris Ali
> Priority: Critical
> Fix For: 0.3
>
>
> Falcon provides LateRerunService and RetryService to automatically handle
> late data reruns and instance failure correspondingly, for both process and a
> feed instance based on the policies like periodic, back-off etc.
> The service supports switchable queues to handle the messages, currently
> Retry Service uses InMemoryQueue which is built over Java's DelayQueue. A
> case where if the delay (delayedMessage) in message is greater than the
> existing message in the queue is not handle, and the service just stops
> enqueuing or dequeing the messages. Hence Falcon stops all the failed
> instance retries.
> A fix in the compareTo method of the event message is required.
> The fix can be back-ported from Ivory.
