-------------------------------------
Summary: 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
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.
