-----------------------------------
Summary: Increase retry interval for non-progressing coordinator
action using exponential backoff concept
Key: OOZIE-1402
URL: https://issues.apache.org/jira/browse/OOZIE-1402
Project: Oozie
Issue Type: Improvement
Affects Versions: trunk
Reporter: Mona Chitnis
Assignee: Mona Chitnis
Priority: Minor
Fix For: trunk
Currently every coordinator action is retried to check data directory in the
next minute.
We could make it better by waiting longer for coordinator action that is not
progressing (i.e. find no new directory) for repeated retries
The waiting time should start from 1 minute for X retries. Then the action
should wait for 2 minutes. After X retries it should wait for 3. The same way
it will go to some max-wait-time and stay there until timeout
