------------------------------------
Summary: Add a way to stream the logs for only the last x hours
Key: OOZIE-1716
URL: https://issues.apache.org/jira/browse/OOZIE-1716
Project: Oozie
Issue Type: New Feature
Affects Versions: trunk
Reporter: Robert Kanter
When a user has a busy cluster and long running coordinator jobs, streaming the
logs can be really slow. In this situation, the user is typically only
interested in the latest logs and doesn't care about logs from a while ago.
So, we can speed this up by adding a parameter or something to the log
streaming API to only fetch the logs from the last x hours. The log files roll
over every hour, so this should be pretty straightforward. We can also prepend
a message to the logs streamed back mentioning that only the last x hours of
logs are included. The existing way of getting all of the logs should remain
unaffected and still work.
