Christopher Tubbs commented on ACCUMULO-3617:
---------------------------------------------
I'm just trying to get an understanding of what a fix would look like. It
sounds like [~elserj] and [~ecn] would be in favor of eliminating this log
message for all successful permission checks (regardless of the request type),
and that we should ensure sufficient logging is done elsewhere, when each
individual action is actually performed.
> unloadTablet log message in TabletServer is spammy w/o purpose

> Key: ACCUMULO-3617
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3617
> Project: Accumulo
> Issue Type: Improvement
> Components: tserver
> Affects Versions: 1.5.2, 1.6.2
> Reporter: Josh Elser
> Priority: Minor
> Labels: newbie
> Fix For: 1.7.0

> 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.
