Subject [jira] [Resolved] (CASSANDRA-5100) Create different log entry if dropped mutation is a hint
Date Thu, 03 Jan 2013 15:56:13 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-5100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis resolved CASSANDRA-5100.
---------------------------------------

    Resolution: Not A Problem

# There is no difference to the recipient to signify that a given Mutation is a hint, nor
should there be
# The hint owner will not remove the hint until it is delivered, so there's nothing particularly
serious about dropping a hint a second time, or a third.  (If anything, the first time is
the worst since it forces hint creation; after that, it can be dropped "for free" as far as
the rest of the system is concerned.)

>          Components: Core
>    Affects Versions: 1.2.0
>            Reporter: Patrick McFadin
>            Priority: Minor

> When a mutation is dropped, you see an INFO log line like this:
> MessagingService.java (line 607) 816 MUTATION messages dropped in last 5000ms
> It would be helpful to know that the mutation was a local hint being dropped. Since this
is much more severe case of a dropped mutation, I also think it should be a WARN and not an
INFO.
