Andrew Wang updated HADOOP-12759:
---------------------------------
Resolution: Fixed
Fix Version/s: 2.9.0
Target Version/s: 2.9.0 (was: 2.8.0)
Status: Resolved (was: Patch Available)
Pushed to trunk and branch-2, the original patch HADOOP-12702 is not in
branch-2.8 so I'm updating the target/fixed version to 2.9.0.
Thanks for the contribution Daniel and review Robert!

> The RollingFileSystemSink only rolls over to a new directory if a new metrics
> record comes in. The issue is that HDFS does not update the file size until
> it's closed (HDFS-5478), and if no new metrics record comes in, then the file
> size will never be updated.
> This JIRA is to add a background thread to the sink that will eagerly close
> the file at the top of the hour.
