Subject [jira] [Commented] (ACCUMULO-3617) unloadTablet log message in TabletServer is spammy w/o purpose
Date Wed, 18 Mar 2015 19:03:38 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14367679#comment-14367679
] 

Josh Elser commented on ACCUMULO-3617:
--------------------------------------

IMO, is there a purpose to auditing unloadTablet with the understand that the master will
repeatedly spam it until the server actually responds to the request? Without more information,
I don't think it makes sense to log it at all. If it actually included the extent in question,
I could see it at TRACE.

Given that it's in a checkPermission block, I think the intent was not to debug the fact that
the server saw an unloadMessage, but more that it allowed an unloadMessage which, IMO, is
useless.

> Looking at TabletServer logs, the following message can be overwhelming:
> {noformat}
> 2015-02-24 01:57:34,723 [tserver.TabletServer] DEBUG: Got unloadTablet message from user:
!SYSTEM
> {noformat}
> This message alone tells us nothing (no context about the tablet(s) requested to be unloaded,
only that there was a request to unload a tablet), and can appear in the log upwards of 20
times a millisecond.
> It might be better if the TabletServer did...
> * Batched log messages "N unloadTablet requests in $duration"
> * Include extent to unload
> * Kill the log message entirely.
