[jira] [Commented] (CASSANDRA-11090) Hinted Handoff loop

["Aleksey Yeschenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-11090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15505264#comment-15505264 ] 

Aleksey Yeschenko commented on CASSANDRA-11090:
-----------------------------------------------

That doesn't seem like a problem to me - that's the way it should work. The original issue was causing empty hint files to be created and deleted every 10 seconds, this seems to be processing non-empty hint files every minute, as intended.

> After the hints executor finishes sending hints, another hints file is created for the same host, which is then processed on the next go around. This continues indefinitely. The new hint files are empty, so there shouldn't be any network traffic. However, there's still unnecessary hint activity, and the hint crc file isn't deleted in the 3.0 branch after hints are dispatched (but is in trunk), so any hint activity will trigger ~8640 files being created per day until the node is restarted. Restarting the node fixes the problem, after the existing hint files are processed. 
> This can be duplicated on cassandra-3.0 to trunk with this script: https://gist.github.com/bdeggleston/13fbb9e70c0c0bd277c7
