Summary: Support re-tries for timed-out instances
Key: FALCON-1677
URL: https://issues.apache.org/jira/browse/FALCON-1677
Project: Falcon
Issue Type: Bug
Reporter: Pallavi Rao
Currently, Falcon retries only on failure. We should extend support in case of
timed-out instances too. Earlier, since we were relying on post-processing to
notify the instance status, this was not possible. Now that Falcon relies on
Oozie JMS notifications, we can support retries for timed out instances too.
If a dataset is expected to get delayed for a long time, the user is currently
forced to supply a large timeout value. This is an overhead in terms of Oozie
having to poll for that long. If we introduce retries, the timeout can be a
reasonable value with periodic/exponential back-off retries.
